Implementation of Simple Binary Search Tree in C++ Data Structure Binary Search Tree is a special type of binary tree which is designed to store elements in a specific order. In a binary search tree, the left sub-tree of a node contains only nodes with keys lesser than the node’s key.
The right sub-tree of a node contains only nodes with keys greater than the node’s key. Here's a simple implementation of Binary Search Tree in C++ language:#include using namespace std;struct Node{ int data; Node *left; Node *right;};// Creating a new node Node* new Node(int val){ Node* temp = new Node(); temp->data = val; temp->left = NULL; temp->right = NULL; return temp;}// Inserting a new node into the BSTNode* insert(Node* root, int val){ if(root == NULL) return newNode(val); if(val < root->data) root->left = insert(root->left, val); else if(val > root->data) root->right = insert(root->right, val); return root;}// In-order traversal of BSTvoid inorder(Node* root){ if(root == NULL) return; inorder(root->left); cout << root->data << " "; inorder(root->right);}//
Main functionint main(){ Node* root = NULL; root = insert(root, 5); insert(root, 3); insert(root, 2); insert(root, 4); insert(root, 7); insert(root, 6); insert(root, 8); inorder(root); return 0;} 2. Implementation of Simple Queue and Stack in C++ Data StructureA Stack is a LIFO (Last In First Out) data structure where the element that is inserted last will be the first one to come out. On the other hand, a Queue is a FIFO (First In First Out) data structure where the element that is inserted first will be the first one to come out. Here's a simple implementation of Stack and Queue in C++ language:#include using namespace std;#define MAX 100int top = -1; int stack[MAX];// Pushing an element into the stackvoid push(int val){ if(top >= MAX-1){ cout << "Stack Overflow" << endl; return; } stack[++top] = val;}// Removing an element from the stackint pop(){ if(top < 0){ cout << "Stack Underflow" << endl; return -1; } int val = stack[top--]; return val;}// Checking if the stack is empty or notbool isEmpty(){ return top < 0;}// Displaying all elements in the stackvoid displayStack(){ for(int i=top;i>=0;i--) cout << stack[i] << " "; cout << endl;}// Implementing a Queueint front = -1; int rear = -1; int queue[MAX];// Adding an element to the Queuevoid enqueue(int val){ if(rear == MAX-1){ cout << "Queue Overflow" << endl; return; } if(front == -1) front = 0; queue[++rear] = val;}// Removing an element from the Queueint dequeue(){ if(front == -1 || front > rear){ cout << "Queue Underflow" << endl; return -1; } int val = queue[front++]; return val;}// Checking if the Queue is empty or notbool isQueueEmpty(){ return front == -1 || front > rear;}// Displaying all elements in the Queuevoid displayQueue(){ for(int i=front;i<=rear;i++) cout << queue[i] << " "; cout << endl;}// Main functionint main(){ push(5); push(3); push(2); push(4); push(1); displayStack(); cout << pop() << endl; cout << pop() << endl; displayStack(); enqueue(5); enqueue(3); enqueue(2); enqueue(4); enqueue(1); displayQueue(); cout << dequeue() << endl; cout << dequeue() << endl; displayQueue(); return 0;}

Create a decision table
A large technology company receives thousands of applications per day from software engineers who hope to work for that company.
To help manage the constant flow of applications, a process has been created to streamline identifying applicants for specific openings as they occur.
Those applications that are not in an approved file format are discarded and not processed in any way.
All applications are first fact-checked automatically by detecting any inconsistencies with the application and the resume, as well as other resume sites available online.
For any applications with more than one inconsistency, the application is automatically rejected as untruthful.
Next, the application is checked against the database of other applications already in the system. If such an application exists, the older application is purged and the new application continues processing.
Any applications that do not contain at least 15 of the top 200 keywords that the company is looking for are rejected.
Next, the phone numbers of references are checked to ensure they are a valid, working phone number.
These applicants are then retained in a searchable database.
When managers send a hiring request, the fifty best applications that most closely match the desired attributes are sent to the manager.
That manager selects the top 10 applications, which are then screened for bad credit, with credit scores below 500 eliminated from the hiring process. If there are at least 5 remaining candidates, they are all invited to participate in phone interviews.
If there are fewer than 5 remaining candidates, the next 10 best matches are added to the pool and screened for poor credit, and any remaining candidates are invited to participate in phone interviews.

Explain the role of and where to use FTT and FTM. Provide at least one example scenario that demonstrates FTT and FTM principles.
FTT (Fiber to the Terminal) and FTM (Fiber to the Mast) are two distinct optical fiber network design implementations that serve to improve the quality of service and reliability of networks. In this answer, the roles of FTT and FTM and where they are used will be explained. One example scenario that demonstrates FTT and FTM principles will be given.FTT (Fiber to the Terminal)FTT (Fiber to the Terminal) refers to a fiber optic cable that terminates at a distribution point, serving a single building or a few buildings in the case of multiple occupancy buildings.
A terminal is installed at the location where the fiber terminates, and it converts the fiber optic signal to the electrical signal that is needed to power the customer's devices. The customer is given their network interface device (NID) and an Ethernet cable to connect their devices to the NID. FTT can be used in areas where there are several buildings, and the distance between them is short.The role of FTT is to enhance data transmission speed and reduce latency and signal loss. By installing FTT networks, service providers can provide faster, more reliable broadband services. FTT networks can be used to provide services such as video on demand, VoIP, and high-speed Internet. FTTH, which stands for Fiber to the Home, is a type of FTT that terminates at the customer's premises.FTM (Fiber to the Mast)FTM (Fiber to the Mast) refers to an optical fiber cable that terminates at the base of a wireless mast or antenna. FTM provides high-speed Internet access to wireless carriers, who can then use it to provide services to their customers. The mast is connected to the FTM fiber cable through a radio frequency (RF) connection, which is used to transmit the signal to the customer's devices.
FTM is used in locations where there are no wired connections, and it is not possible to install wired connections.The role of FTM is to provide wireless carriers with fast and reliable data transmission capabilities. FTM can be used to provide a variety of services, including wireless broadband and voice services, mobile data services, and 4G and 5G services. By installing FTM networks, wireless carriers can improve the quality of their services, provide better coverage, and reduce network congestion.

if i have the client files for a game can i create a private server for that game with the flies i have?
In most cases, simply having the client files for a game is not sufficient to create a private server. Creating a private server typically requires access to the server-side code and infrastructure, which is typically owned and managed by the game's developer or publisher.
The server-side code is responsible for managing the game's logic, multiplayer functionality, and other important aspects.
Without the server-side code and infrastructure, it is challenging to create a functional private server. The server-side code is usually proprietary and not publicly available, as developers want to maintain control over the game's online experience and prevent unauthorized servers from operating.
However, there have been instances where game enthusiasts and developers have reverse-engineered server software for certain games, allowing them to create private servers. These instances are usually limited to older games or games where the server-side code has been leaked or made available through other means. It is important to note that creating private servers without proper authorization or violating the game's terms of service may be considered a breach of intellectual property rights and can have legal consequences.
In summary, while having client files can provide valuable information, creating a private server for a game typically requires access to the server-side code and infrastructure, which is not readily available to the general public.

2. How do society and culture influence the development of S & T?
B.
1. Research an article that talks on Filipino Indigenous knowledge. Discuss the
connection of said knowledge to science and technology.
2. Give your own thought about this statement: "We really respect the indigenous
knowledge. These traditional values of dealing with illness have validity, even if we
don’t understand the scientific basis." Ray White
Indigenous science plays an important role in the development of science and technology (S&T) in the Philippines. It influences the development of S&T in several ways. Firstly, it provides an important basis for traditional knowledge that can be used in the development of new technologies.
Secondly, it provides an understanding of the natural environment and the relationships between humans and the natural world, which can help inform scientific research and development. Finally, it contributes to the development of a national identity that is rooted in the unique cultural heritage of the Philippines.Society and culture influence the development of S&T in many ways. For example, society provides the demand for new technologies, while culture influences the way in which these technologies are designed, developed, and used. Additionally, cultural values and beliefs may impact the types of research that are pursued and the way in which scientific discoveries are communicated to the public.
An article that talks on Filipino Indigenous knowledge is "Ancestral Knowlege in Science and Technology Education in the Philippines: History, Current State, and Directions for the Future" by Cynthia C. Bautista. The connection of said knowledge to science and technology is that it can be used to develop new technologies that are appropriate for local contexts, promote environmental sustainability, and recognize the importance of traditional knowledge in the modern world.My thoughts about the statement "We really respect the indigenous knowledge. These traditional values of dealing with illness have validity, even if we don’t understand the scientific basis" by Ray White is that it highlights the importance of respecting traditional knowledge and practices. While science is important, it is not the only way of knowing, and it is important to recognize the value of other ways of knowing that have been developed over centuries of human experience.

Thus, Computer programs process or manipulate data. A piece of data is kept in a variable for processing. Because the value that is stored can be altered, it is called a variable.
A variable is a named storage area that holds a value of a specific data type, to be more precise. A variable, then, has a name, a type, and it keeps a value.
There is a name (or identifier) for a variable, such as radius, area, age, or height. Each variable must have a name in order to be assigned a value (for example, radius=1.2) and to be retrievable (for example, area=radius*radius*3.1416).
A type exists for a variable. Integers (whole numbers) like 123 and -456 are examples of types; doubles are examples of types for floating-point or real numbers.

Vertical integration
Horizontal integration
None of the above
The move of Kodak from simply processing film into digital cameras, as it stretched forward toward the end user (customer), represented a vertical integration strategy.
Vertical integration refers to a company's growth in its own value chain, from producing its raw materials to delivering the finished product to the end consumer. A vertical integration technique entails the merger of two or more firms that are in the same supply chain but at different stages. Horizontal integration refers to the expansion of a company's operations in the same or similar industry. It entails the purchase of a competing firm that produces the same products as the original company. Kodak's move from merely processing film to digital cameras as it stretched forward to the end consumer represented a vertical integration strategy. When a company aims to control the production process from start to finish, vertical integration is used.

"Over the last 5 years, a friend of yours has grown her portfolio
from $2,500 to $6,000. What Excel formula could you use to find the
annual return on her portfolio?
=RATE(5,0,-2500,6000)"
To calculate the annual return on your friend's portfolio over the last 5 years, you can use the Excel formula =RATE(5,0,-2500,6000). This formula calculates the annual interest rate (return) needed to grow an initial investment of -$2,500 (negative because it's an outflow) to $6,000 over a period of 5 years.
The formula has four inputs:
1. Nper (Number of periods): In this case, it's 5 years.
2. Pmt (Payment): The initial investment is -$2,500.
3. Pv (Present value): The current value of the portfolio is $6,000.
4. Fv (Future value): The desired future value is 0 (assuming the investment is liquidated after 5 years).
The formula calculates the annual return on the portfolio by finding the interest rate that, when applied annually for 5 years, results in the portfolio growing from -$2,500 to $6,000. It takes into account the time value of money and provides a single rate that represents the compounded growth rate.
The =RATE(5,0,-2500,6000) formula returns the annual return rate, which you can multiply by 100 to get the percentage. In this case, the annual return rate is approximately 33.47%.
To summarize, the =RATE(5,0,-2500,6000) formula helps you find the annual return rate on your friend's portfolio over the last 5 years, which is around 33.47%.

Which of the following structures is limited to access elements only at structure end?
a. Both Stack and Queue
b. Both Queue and List
c. Both List and Stack
d. All of the other answers
The answer to the given question is option (c) Both List and Stack. What is Stack?A Stack is a linear structure in which insertion and deletion are performed from one end only. It is called the top of the stack. The operations in stack work as Last In First Out (LIFO).
Therefore, the last element that we insert into the stack is the first element that comes out when we remove an element from the stack. It follows a push-pop operation. Push inserts elements at the top and pop deletes elements from the top of the stack.What is List?A list is a collection of items that are ordered and changeable.
A list is one of the most flexible data structures available. It is often described as a sequence of elements where every element has a unique position and index. A list allows the creation of a series of data that can be accessed by an index. The position of the element defines the index. The first element of the list starts with 0 and the second with 1, and so on. There are two types of lists - singly linked lists and doubly linked lists.Therefore, Both List and Stack structures are limited to access elements only at structure end.

What are the Attitude Control System Errors
that impacted the TIMED NASA mission?
The Attitude Control System (ACS) is a system that governs the spacecraft's position and orientation in space. When it comes to the TIMED mission, the Attitude Control System (ACS) had two major issues, which are elaborated below:1. A pitch rate gyro drift: It was discovered that one of the pitch rate gyros was affected by a constant drift, which was most likely caused by radiation exposure.
This resulted in attitude estimation errors, which meant that the spacecraft was pointed in the wrong direction.2. An ACS magnetic sensor failure: A sudden voltage spike caused a magnetic sensor's permanent failure, which then resulted in large attitude errors. The ACS magnetic sensor is an important component of the ACS since it determines the spacecraft's orientation in space.
The sensor in question was unable to estimate the correct magnetic field vector and, as a result, could not calculate the spacecraft's orientation correctly. Both the pitch rate gyro drift and the magnetic sensor failure led to the spacecraft's inability to maintain its orientation in space.

Question 4 2 pts Suppose that we have a computer that can test 205 keys each second. What is the expected time (in years) to find a key by exhaustive search if the key space is of size 22⁹0 1.80 X 10^60 1.65 X 10^60 O 1.70 X 10^60 1.26 X 10^65
The expected time in years is 1.80 x 10^60.The correct answer is option A.
To find the expected time to find a key by exhaustive search, we can divide the size of the key space by the number of keys tested per second.
The size of the key space is 2^290, and the computer can test 2^65 keys each second.
Therefore, the expected time in seconds is:
(2^290) / (2^65) = 2^(290-65) = 2^225
To convert this into years, we need to divide it by the number of seconds in a year. There are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day. Additionally, there are 365 days in a non-leap year.
So, the number of seconds in a year is:
60 seconds/minute * 60 minutes/hour * 24 hours/day * 365 days/year = 31,536,000 seconds/year
Finally, we can calculate the expected time in years:
(2^225) / 31,536,000 = 1.80 x 10^60 years
Therefore, the answer is option A. 1.80 x 10^60.

solving this in C++ language by using array
You take the information of 3 students, each student has 3 tests that bring up the total, the highest score and the lowest score for each student in his spirit
The code allows you to input the scores of 3 students for 3 tests and calculates the total, highest, and lowest scores for each student. You can customize the number of students and tests by modifying the constants NUM_STUDENTS and NUM_TESTS.
Here's an example of solving this problem using arrays in C++:
#include <iostream>
const int NUM_STUDENTS = 3;
const int NUM_TESTS = 3;
int main() {
int scores[NUM_STUDENTS][NUM_TESTS];
// Input scores for each student and test
for (int i = 0; i < NUM_STUDENTS; i++) {
std::cout << "Enter scores for Student " << i + 1 << ":\n";
for (int j = 0; j < NUM_TESTS; j++) {
std::cout << "Test " << j + 1 << ": ";
std::cin >> scores[i][j];
}
}
// Calculate total, highest, and lowest scores for each student
for (int i = 0; i < NUM_STUDENTS; i++) {
int total = 0;
int highest = scores[i][0];
int lowest = scores[i][0];
for (int j = 0; j < NUM_TESTS; j++) {
total += scores[i][j];
if (scores[i][j] > highest) {
highest = scores[i][j];
}
if (scores[i][j] < lowest) {
lowest = scores[i][j];
}
}
std::cout << "Student " << i + 1 << ":\n";
std::cout << "Total score: " << total << std::endl;
std::cout << "Highest score: " << highest << std::endl;
std::cout << "Lowest score: " << lowest << std::endl;
}
return 0;
}
In this code, we define a 2D array scores to store the scores of each student for each test. We then use nested loops to input the scores for each student and test. Next, we iterate over each student and calculate the total, highest, and lowest scores by traversing the scores array. Finally, we output the calculated values for each student.

A condition is often a comparison between two values.
All of these are true about conditional statements.
Conditional statements are used for decision-making processes in programming. They are composed of two parts: the condition and the action to take if the condition is true. If the condition is not satisfied, no action is taken.
In programming, conditional statements are written using the "if-then" statement format, which is also referred to as the "if-then-else" format in more complex cases. It's worth noting that not all programming languages use the same syntax for writing conditional statements. Here are a few things that are true about conditional statements: Conditional statements, also known as if/then statements, are a way of making decisions based on a set of conditions. When the condition is true, a specific action is taken.
They're often written in the form of "if this condition is true, then do this task. "If the answer to a question is true, the conditional statement performs a task. If the condition is not true, the action associated with it is not performed, and the program continues on its way. They do not use curly braces [] to mark the beginning and end of the yes/no question. However, they do use parentheses, {}, or other syntax in the language to enclose the condition and the code block. All in all, the third statement is not true about conditional statements.
