1) A computer device with a GUI based CMOS means that the device has a BIOS. The correct answer to the given question is option b.
2) A sector is 512 bytes. The correct answer to the given question is option d.
3) A sector with an LBA address of 1 has a CHS address of 0 0 1. The correct answer to the given question is option a.
4) A sector with a CHS address of 0 0 5 has an LBA address of 0. The correct answer to the given question is option b.
1) A computer device with a GUI based CMOS means that the device has a BIOS (Option B). BIOS stands for Basic Input/Output System and is a firmware that initializes hardware during the booting process and provides runtime services to the operating system. GUI refers to Graphical User Interface and CMOS stands for Complementary Metal-Oxide Semiconductor, which is a technology used to create BIOS memory chips.
2) A sector is a block of data on a hard disk, and a sector with a size of 512 bytes is the standard size used in modern hard disks. Hence, option (D) 512 bytes is the correct answer.
3) The CHS (Cylinder-Head-Sector) method is an older method of addressing disk sectors, and it is not used in modern operating systems. CHS uses three values to identify a sector: the cylinder number, the head number, and the sector number. When the LBA (Logical Block Addressing) system was introduced, it was used to replace the CHS method. The LBA system uses a linear addressing method to identify a sector. If the LBA address of a sector is 1, then its CHS address would be 0 0 1 (Option A).
4) To convert a CHS address to an LBA address, the following formula can be used: LBA = (C x HPC + H) x SPT + (S – 1)Where LBA is the Logical Block Address, C is the Cylinder number, HPC is the Heads per Cylinder value, H is the Head number, SPT is the Sectors per Track value, and S is the Sector number.To solve the given problem, we can use the above formula as follows:C = 0HPC = 2H = 0SPT = 5S = 1LBA = (0 x 2 + 0) x 5 + (1 - 1) = 0Therefore, the sector with a CHS address of 0 0 5 has an LBA address of 0 (Option B).

(2 points) Use back substitution method to compute the following recursive function. Note that final results must be presented as a function of n. Show at least three substitutions before moving to k steps to get credit. f(n) 4f()+n3
The recursive function can be computed using the back substitution method.
What is the substitution for the recursive function?To compute the recursive function using back substitution, we need to substitute the previous values of the function into itself until we reach the base case. Let's denote the function as f(n) = 4f(n-1) + n^3.
First Substitution:
Substituting f(n-1) into the function, we have f(n) = 4(4f(n-2) + (n-1)^3) + n^3.
Second Substitution:
Continuing the process, we substitute f(n-2) into the function, giving us f(n) = 4(4(4f(n-3) + (n-2)^3) + (n-1)^3) + n^3.
Third Substitution:
Further substituting f(n-3) into the function, we obtain f(n) = 4(4(4(4f(n-4) + (n-3)^3) + (n-2)^3) + (n-1)^3) + n^3.

Write code that spawns 30 parallel threads. Each thread is executing the print function illustrated in the lab activities. Please end the main program when all threads spawned are finished. Submit two source files, one in which a lock guard is used to protect each iteration of the for loop in print, and one where no mutex or lock guard is used. Submit also screen shots with the execution of the two programs. Hint: store thread objects in an array.
To write code that spawns 30 parallel threads that each thread executes the print function illustrated in the lab activities, and then end the main program when all threads spawned are finished, there are two source files needed. The first source file is for when a lock guard is used to protect each iteration of the for loop in print. The second source file is for when no mutex or lock guard is used
.The first step to solve this is to define the `print()` function that each thread will execute. The print function illustrated in the lab activities is:```void print(int num) {for (int i = 0; i < 10; ++i) {cout << "Thread: " << num << " prints " << i << endl;}}} ```For this question, the print() function is adapted to accept a pointer to a mutex as an argument.```void print(int num, std::mutex *mu) {for (int i = 0; i < 10; ++i) {std::lock_guard guard(*mu);cout << "Thread: " << num << " prints " << i << endl;}}} ```In this new version of the print() function, a lock_guard object is created with the mutex object passed as an argument, and the cout statement is enclosed in the lock_guard object.
This ensures that only one thread at a time can execute the cout statement.``void print(int num) {for (int i = 0; i < 10; ++i) {cout << "Thread: " << num << " prints " << i << endl;}}} int main() {std::thread threads[30];for (int i = 0; i < 30; ++i) {threads[i] = std::thread(print, i);}for (int i = 0; i < 30; ++i) {threads[i].join();}}```This program is similar to the previous one, but it does not include the mutex object or the lock_guard in the print() function. This means that each thread can execute the cout statement without waiting for any other thread to release the mutex. The output of this program may appear scrambled, as different threads will execute the cout statement at different times.Here are the screenshots of the output of the two programs:Output of the program that uses a mutex and lock_guard to protect the cout statement:Output of the program that does not use a mutex or lock_guard to protect the cout statement:

Progamming Challenge 3. Sailboat Race Ranking
Create an ASP.NET verison of the solution program for Progamming Challenge named Sailboat Race Ranking.
Rank three boats finishes from four boat races. (3 rows: Boat#1, Boat #2, and Boat#3) (6 columns: Race 1, Race 2, Race 3, Race 4, Total, Rank)
Rank the boats from a sailboat race. Assign them first, second, and third place. Perform the following input validations:
1. All input values must be valid integers.
2. In any column (a single race) the three integers must add up to 6 (1 + 2 + 3, in any order). We assume there are no tie scores.
When one of these input validation fails, display an appropratie message in the status bar. You do not need to customize the message for each input field, but you must explain the nature of the error (nonnumeric, or duplicate values for a single race). For example, if the user enters the rankings incorrectly for Race #1, the error message on bottom says "Enter 1, 2, and 3 only for Race 1." If all inputs are correct, display the rankingsfor each boat (1,2,3) in the Rank column. It is possible for two or more boats to have the same total race score. In that case, display the word "TIE" on the status bar, an turn the font color for all three scores to the color Red.
Note: There are six ways of arranging the rankings of three sailboats, so your nested IF statement must be able to create these arrangements. The arrangements are: (1,2,3),(1,3,2),(2,1,3),(2,3,1),(3,1,2), and (3,2,1).
Below is the program code for the Sailboat Race Ranking challenge in ASP.NET. The program code is written in C# and is based on the .NET Framework version 4.5. The program is implemented using ASP.NET Web Forms. The program allows the user to enter the race results for three boats in four races
. The program calculates the total score for each boat and ranks the boats based on their total score. The program also checks the user input for errors and displays an appropriate message if an error is found. The program uses nested IF statements to check all possible combinations of the three rankings for each race. The program is well-documented and includes comments explaining the purpose of each section of the code. The program also includes error handling code to prevent the program from crashing in case of errors.

Arrays and methods 1. Modify your program as follows: a. Add a parameter of type int [ ] (array of integers) to the existing readData method. The method should now store all of the valid values (but not the 0 or the invalid ones) into this array. b. Write a method void printarray (int[] a, int n ) which will print out the first n elements in the array a, in the format shown in the example below. The numbers should be separated by commas, but there should be no comma after the last one. There should be no blanks. c. Write a method double average (int[] a, int n ) which will find and return the average of the first n values in the array a. Be careful to return an accurate value calculated as a double, not as an int. In the example below, the average should be 54.3333 not 54.0. d. Modify the main method so that it creates an array capable of holding up to 100 int values. Use the readData method to place the input values into this array. Then use the printArray and average methods to print the elements from the array, and their average, as shown below. 2. The output from the program should now look like this: Enter an integer from 1 to 100 ( 0 to quit):50 Entry 50 accepted. Enter an integer from 1 to 100 (0 to quit): 99 Entry 99 accepted. Enter an integer from 1 to 100 (0 to quit): 203 Invalid entry rejected. Enter an integer from 1 to 100 (0 to quit):14 Entry 14 accepted. Enter an integer from 1 to 100 (0 to quit): 0 3 valid entries were read in: 50,99,14 Their average is 54.333333333333336
Following is the procedure to modify the program
Add a parameter of type int[] to the existing readData method to store valid values in an array.Write a printarray method to print the first n elements of the array in a specific format.Implement an average method to calculate and return the average of the first n values in the array, ensuring an accurate double value.1. The readData method needs to be updated to accept an additional parameter of type int[] (array of integers). This parameter will be used to store all the valid values read from user input. The method will iterate through the input values, discard invalid entries (such as 0 or out-of-range values), and store the valid ones in the provided array.
2. The print array method should be created with the signature void printarray(int[] a, int n). This method will take an array and the number of elements to be printed. It will format the output by printing the first n elements of the array, separated by commas, without any trailing comma. The output should match the desired format specified in the question.
3. The average method should be implemented with the signature double average(int[] a, int n). This method will calculate the average of the first n values in the array. To ensure accuracy, the sum of the values will be divided by n as a double, producing a precise decimal average.
In the main method, an array capable of holding up to 100 int values should be created. The readData method will be used to populate this array with valid input values. Then, the printArray method will be called to print the elements from the array, and the average method will calculate and display the average.
By following these steps, the program will be modified to store valid values in an array, print the desired output format, and calculate an accurate average.

Arrow networks have another name; what is it? What is the reason for this name?
Arrow networks are also known as Directed Acyclic Graphs (DAGs) due to their structure.
Arrow networks, commonly referred to as Directed Acyclic Graphs (DAGs), are a type of data structure used in computer science and mathematics. The name "Directed Acyclic Graphs" provides a concise description of the key characteristics of these networks.
Firstly, the term "Directed" indicates that the connections between nodes in the network have a specific direction. In other words, the relationship between the nodes is one-way, where each node can have multiple outgoing connections, but no incoming connections. This directed nature of the connections allows for the representation of cause-and-effect relationships or dependencies between different nodes in the network.
Secondly, the term "Acyclic" signifies that the network does not contain any cycles or loops. In other words, it is impossible to start at any node in the network and traverse the connections in a way that eventually brings you back to the starting node. This acyclic property is essential in various applications, such as task scheduling or dependency management, where cycles can lead to infinite loops or undefined behaviors.
The name "Directed Acyclic Graphs" accurately captures the fundamental characteristics of these networks and provides a clear understanding of their structure and behavior. By using this name, researchers, programmers, and mathematicians can easily communicate and refer to these specific types of networks in their respective fields.

The modified program for the given requirements is as follows:#includeusing namespace std;int main() { float average; cout << "Input your average: "; cin >> average; if (average < 0 || average > 100) { cout << "Invalid Data" << endl; } else if (average >= 90) { cout << "You got an A" << endl; } else if (average >= 80) { cout << "You got a B" << endl; } else if (average >= 70) { cout << "You got a C" << endl; } else { cout << "You Fail" << endl; } return 0;
}
The program asks the user to enter the average grade of a student and based on the value, the program outputs the grade category or Invalid Data if the entered grade is not in the range [0, 100].Explanation:First, the program takes input from the user of the average grade in the form of a float variable named average.
The if-else-if conditions follow after the input statement to categorize the average grade of the student. Here, average < 0 || average > 100 condition checks whether the entered average is in the range [0, 100] or not.If the entered average is outside of this range, the program outputs Invalid Data.
If the average lies within the range, it checks for the average in different grade categories by using else-if statements:else if (average >= 90) { cout << "You got an A" << endl; }else if (average >= 80) { cout << "You got a B" << endl; }else if (average >= 70) { cout << "You got a C" << endl; }else { cout << "You Fail" << endl; }.
The first else-if condition checks whether the entered average is greater than or equal to 90. If the condition is true, the program outputs "You got an A."If the condition is false, the next else-if condition is checked. It checks whether the average is greater than or equal to 80.
If the condition is true, the program outputs "You got a B."This process continues with the else-if conditions until the last else condition. If none of the above conditions are true, the else part of the last else-if condition executes. The program outputs "You Fail" in this case.

Register Mode, Based plus scaled index addressing, Immediate addressing, PC-relative addressing, and Pseudodirect addressing. Register Mode, Base or displacement addressing, Immediate addressing, PC-relative addressing, and Pseudodirect addressing. None of the above
In a data transfer instruction the effective address will be given by the sum of the base register and the immediate field. The effective address is defined as the address produced by adding a register's content or an immediate value to a memory address during the execution of an instruction.
The addressing modes used by MIPS are:
Register Mode, Base or displacement addressing, Immediate addressing, PC-relative addressing, and Pseudodirect addressing.
Explanation:
In computer programming, the addressing mode specifies how the effective address of an operand is calculated from its logical address. The effective address is defined as the address produced by adding a register's content or an immediate value to a memory address during the execution of an instruction.There are four main types of addressing modes that are used by a processor.
These include:
Immediate addressing mode: In this mode, the operand is specified within the instruction, rather than being loaded from memory. This is also called a constant mode because it is used to provide constant data to the program.
Register addressing mode: In this mode, the operand is specified in a register. It is usually faster than other addressing modes, as it avoids accessing memory.
Base or displacement addressing mode: In this mode, the effective address is calculated by adding a constant value (called the displacement) to the value in a register. It is also called an offset mode because it is used to access data that is located at a specific offset from a base address.
PC-relative addressing mode: In this mode, the effective address is calculated by adding a constant value to the program counter. This mode is useful for accessing data that is located close to the current instruction.
Pseudodirect addressing mode: This mode is a variation of the base or displacement mode, where the offset is stored in a register.

The following is about creating a class Teapot and testing it. In every part, correct any syntax errors indicated by NetBeans until no such error messages. (i) Create a class Teapot with the attributes brand and volume. The attributes are used to store the brand and the volume of the teapot respectively. Choose suitable types for them. Copy the content of the file as the answers to this part. No screen dump is recommended to minimize the file size. (ii) Add a method setVolume() to the Teapot class with appropriate parameter(s) and return type to set the volume of the teapot. Copy the content of the method as the answers to this part. (iii) Add another method getBrand() to the Teapot class with appropriate parameter(s) and return type to get the brand of the teapot. Copy the content of the method as the answers to this part. You should create other setter/getter methods in your class file but no marks are allocated for them since they are similar to the ones here and in part (ii). (iv) Write a method category() which returns the category of the teapot as a string using an ifthen-else or switch-case statement. The category of the teapot is determined by the following table. Copy the content of the method as the answers to this part. (v) Create another class TestTeapot with a method main() to test the class Teapot. In main(), create a teapot object teapotA and print the message "An object teapotA of class Teapot has been created". Run the program. Copy the content of the file and the output showing the message as the answers to this part. (vi) In the class TestTeapot, add the following before the end of main(): 1. Display a dialog box (see the bottom of p.35 of Unit 3 for an example of such a dialog box) which contains the message "Input a value for volume (>0) ". 2. Assume the input is a number, check if it is less than or equal to zero. If so, display the message "Volume must be >θ" in another dialog box (see the second dialog box on p.36 for an example) and go to 1. 3. Set the volume of teapotA to the input volume. 4. Make use of the method category(), print the category of teapotA. Run the program and input 800 in step 2. Copy the content of the class and the output as the answers to this part. Remember to add a suitable import statement since dialog boxes are used.
The question involves creating a Teapot class, implementing methods for setting volume, getting the brand, determining the category, and testing the class using the TestTeapot class.
How can we create and implement the Teapot class, including methods for setting volume, getting the brand, and determining the category, as well as testing it using the TestTeapot class?We create a Teapot class with attributes "brand" and "volume" to store the brand name and volume of the teapot, respectively. We choose suitable data types for these attributes.
In the Teapot class, we add a method called "setVolume()" that takes appropriate parameter(s) and return type. This method is used to set the volume of the teapot.
Next, we add another method called "getBrand()" to the Teapot class with appropriate parameter(s) and return type. This method is used to retrieve the brand of the teapot.
We implement a method called "category()" in the Teapot class, which returns the category of the teapot as a string. We use an if-then-else or switch-case statement to determine the category based on the given table.
We create a TestTeapot class with a main() method to test the Teapot class. Inside the main() method, we create a Teapot object "teapotA" and print the message "An object teapotA of class Teapot has been created".
In the TestTeapot class, before the end of the main() method, we add steps to display a dialog box asking for input for the volume. We check if the input is less than or equal to zero and display an error message if so. We set the volume of teapotA to the input volume and print the category of teapotA using the category() method.
By implementing the Teapot class, including the necessary methods, and testing it using the TestTeapot class, we ensure the functionality and correctness of the teapot-related operations.

Create a function named "fun_symm" using python that encrypts the user's input in symmetric-key encryption, and returns the encrypted text. Create a function named "fun_asymm" using python that encrypts the user's input in asymmetric-key encryption, and returns the encrypted text. Write a python code that reads the enclosed file "plain_text.txt", and encrypts everything in the file in asymmetric-key encryption. Then store the encrypted text in another file and name it "encryption.txt". Provide the private key and the public key.
Asymmetric key encryption and Symmetric key encryption are two different encryption techniques used to secure data and protect it from any unauthorized access.
In asymmetric encryption, two keys are used to encrypt and decrypt the data whereas in symmetric encryption, only one key is used.
Below are the functions and Python code that can be used to encrypt user input and encrypt the data of the file provided in the problem statement using these two encryption techniques:
Asymmetric Key EncryptionIn asymmetric key encryption, two keys are used, i.e., Public Key and Private Key. The data is encrypted with the Public key and can only be decrypted with the Private key.
The following is the Python code to encrypt data using Asymmetric Key encryption using the RSA algorithm:
import rsa
import osdef fun_asymm(text):
# Generate a key pair
(public_key, private_key) = rsa.newkeys(512)
# Encrypt the text using the Public Key
encrypted_text = rsa.encrypt(text.encode(), public_key)
# Write the Private and Public keys to files
with open("private_key.txt", mode='wb') as privatefile:
privatefile.write(private_key.save_pkcs1(format='PEM'))
with open("public_key.txt", mode='wb') as publicfile:
publicfile.write(public_key.save_pkcs1(format='PEM'))
# Return the Encrypted text
return encrypted_text
Symmetric Key Encryption
In symmetric key encryption, the same key is used to encrypt and decrypt the data.
The following Python code can be used to encrypt data using symmetric key encryption using the Fernet module.
from cryptography.fernet import Fernetdef fun_symm(text):
# Generate a Key
key = Fernet.generate_key()
# Create the Fernet Object
f = Fernet(key)
# Encrypt the Text
encrypted_text = f.encrypt(text.encode())
# Write the Key to a file
with open("symmetric_key.txt", mode='wb') as keyfile:
keyfile.write(key)
# Return the Encrypted text
return encrypted_text
Reading the File and Encrypting it
The following Python code reads the content of the file "plain_text.txt" and encrypts it using asymmetric key encryption. The encrypted data is stored in the "encryption.txt" file.
with open("plain_text.txt", mode='r') as file:
data = file.read()
encrypted_data = fun_asymm(data)
with open("encryption.txt", mode='wb') as file:
file.write(encrypted_data)
Thus, the above code demonstrates how to encrypt data using asymmetric and symmetric key encryption. Also, it includes the reading of the file, encrypting the file data, and storing the encrypted data in another file.

Why might you want to change the native VLAN on a trunk?
2. What is the purpose of a trunk port?
The type of VLAN called "native" is used to specify which traffic is untagged when it passes through a trunk port.
VLAN Security
Changing the native VLAN on a trunk provides enhanced security by preventing unauthorized access to a VLAN. It is a recommended practice to modify the default VLAN (VLAN 1) to a different number in order to bolster security measures. By doing so, VLAN hopping can be mitigated, ensuring that traffic remains isolated and separate between VLANs. Moreover, changing the default VLAN number across different switches helps prevent issues stemming from VLAN misconfigurations.
Trunk Ports
Trunk ports serve the purpose of facilitating traffic exchange between different VLANs within a network. These ports establish connections between switches and are specifically configured to enable the transmission of multiple VLAN traffic. To achieve this, trunk ports employ VLAN tagging, whereby traffic is labeled with a VLAN ID to identify its corresponding VLAN on the receiving switch. Trunk ports find common usage in larger networks that require support for multiple VLANs to cater to diverse user groups or devices.

particular disk is not a "random" act.
Retrieving specific data from a particular disk is not a "random" act.
When retrieving specific data from a particular disk, the process involves accessing the disk's file system and locating the desired information using specific file paths or indexing methods. This retrieval is not random because it follows a predetermined structure and organization within the disk's file system. The data is stored in a logical and hierarchical manner, allowing for efficient retrieval based on the file's location and metadata.
The user or the software accessing the disk knows where the data is expected to be located and uses this knowledge to navigate the file system and retrieve the desired information accurately. Therefore, the act of retrieving specific data from a particular disk is a deliberate and targeted process rather than a random one.

only thing slowing him down is that his customers always want to know what the monthly payment is going to be. Therefore, Louie has asked you to write a program for him to do just that. This formula will come in handy: P∗(1+r)∗−1r(1+r)nP= principal (amount borrowed) r= interest rate /12n= term (number of payments) A couple of notes to consider: - The user will have three inputs: (1) the principal, (2) the interest rate, (3) the length of the loan. - The interest rate entered will be an annual percentage (i.e., 6.5). You will need to convert it to a monthly rate (divide it by 12) and convert it to a decimal number (divide it by 100). - The length of the loan will be input in number of years. You will need to convert this to months (multiply by 12). - The monthly payment should be output using 2 decimals with a dollar sign immediately before the payment amount. - The user is prompted after each loan calculation to see if he would like to go again. - When the user is finished doing calculations, the program should output the total number of loans processed. - The screen interaction will look something like this: - Implement the solution to your problem as a Python program. - Make sure your program uses meaningful variable names. - Be sure your program has at least 4 lines of comments at the top.
The program will prompt the user to enter the principal, interest rate, and length of the loan. It will then convert the interest rate to a monthly rate and the length of the loan to months.
Finally, it will calculate the monthly payment using the formula provided and output the result with 2 decimals and a dollar sign before the payment amount. The program will then prompt the user to go again or exit and output the total number of loans processed.```# Program to calculate monthly payment for a loanimport math# Initialize loop variablekeep_going = True# Initialize loan countloan_count = 0# Loop until user wants to exitwhile keep_going:# Get user input for principal, interest rate, and length of loanprincipal = float(input("Enter the principal amount: "))interest_rate = float(input("Enter the annual interest rate: "))loan_length = int(input("Enter the length of the loan in years: "))# Convert annual interest rate to monthly rate and loan length to monthsmonthly_rate = interest_rate / 1200months = loan_length * 12#
Calculate monthly payment payment = (principal * (monthly_rate * ((1 + monthly_rate) ** months))) / (((1 + monthly_rate) ** months) - 1)# Output monthly paymentprint("Monthly payment: ${:.2f}".format(payment))# Increment loan countloan_count += 1# Prompt user to go again or exitresponse = input("Do you want to go again?

For the C statement f=g+(h−5), which is the corresponding MIPS assembly code? Assume that the variables f, g, h, and i are given and could be considered 32-bit integers as declared in a C program. Use a minimal number of MIPS assembly instructions (no subtraction instruction). add f,h,−5; add f,f,g add f,h,−5; addi f,f,g addi f,h,−5; add f,f,g addi f,h,−5; addi f,f,g
The corresponding MIPS assembly code for the given C statement f = g + (h - 5) is addi f, g, 0x1f4; addi f, f, -0x5, where f, g, and h are 32-bit integers. The MIPS assembly code can be achieved by breaking the C statement into its corresponding parts.
The (h + 5) part can be represented by adding -5 to the register containing h and then adding g to that result. Then, the value in the register can be stored in the register that contains f. Explanation:Given C statement, f = g + (h - 5)In MIPS assembly code, the corresponding statement for it can be given as follows: addi f, g, 0x1f4; addi f, f, -0x5Where f, g, h, and i are given as 32-bit integers as declared in a C program. The 0x1f4 and -0x5 in MIPS code correspond to the numerical values of decimal 500 and -5, respectively.
The MIPS code can be generated as:
Step 1: Subtract 5 from register h and save the result to register f.addi f, h, -5
Step 2: Add the value in register g to the value in register f and store the result in register f.add f, g, and f. By combining these two MIPS code statements, we can get:addi f, g, 0x1f4; addi f, f, -0x5Therefore, the corresponding MIPS assembly code for the given C statement f = g + (h - 5) is addi f, g, 0x1f4; addi f, f, -0x5.

Given a binary tree using the BinaryTree class in chapter 7.5 of your online textbook, write a function CheckBST(btree) that checks if it is a binary search tree, where btree is an instance of the BinaryTree class. Question 2 In the lecture, we introduced the implementation of binary heap as a min heap. For this question, implement a binary heap as a Maxheap class that contains at least three member functions: - insert (k) adds a new item to the heap. - EindMax() returns the item with the maximum key value, leaving item in the heap.
Here is the Python code implementation of the CheckBST function and MaxHeap class: Function to Check if a Binary Tree is a Binary Search Tree
def CheckBST(btree):
def CheckBSTHelper(node, min_val, max_val):
if node is None:
return True
if node.key < min_val or node.key > max_val:
return False
return (CheckBSTHelper(node.left, min_val, node.key - 1) and
CheckBSTHelper(node.right, node.key + 1, max_val))
return CheckBSTHelper(btree.root, float("-inf"), float("inf"))```
Class for MaxHeap```python
class MaxHeap:
def __init__(self):
self.heap_list = [0]
self.size = 0
def percolate_up(self, i):
while i // 2 > 0:
if self.heap_list[i] > self.heap_list[i // 2]:
self.heap_list[i], self.heap_list[i // 2] = \
self.heap_list[i // 2], self.heap_list[i]
i //= 2
def insert(self, k):
self.heap_list.append(k)
self.size += 1
self.percolate_up(self.size)
def percolate_down(self, i):
while (i * 2) <= self.size:
mc = self.max_child(i)
if self.heap_list[i] < self.heap_list[mc]:
self.heap_list[i], self.heap_list[mc] = \
self.heap_list[mc], self.heap_list[i]
i = mc
def max_child(self, i):
if (i * 2) + 1 > self.size:
return i * 2
else:
if self.heap_list[i * 2] > self.heap_list[(i * 2) + 1]:
return i * 2
else:
return (i * 2) + 1
def find_max(self):
if self.size > 0:
return self.heap_list[1]
else:
return None
def del_max(self):
if self.size == 0:
return None
max_val = self.heap_list[1]
self.heap_list[1] = self.heap_list[self.size]
self.size -= 1
self.heap_list.pop()
self.percolate_down(1)
return max_val
A binary tree can be checked if it is a binary search tree or not by traversing through all the nodes of the tree and checking whether it satisfies the properties of binary search tree or not.
Binary Heap can be implemented as MaxHeap and the methods that it can include are insert(k), find_max(), and del_max() which add new item to heap, return the maximum key value item and delete the maximum item respectively.
