Answer:
The program is as follows:
my_tuple = (1,2,3,4,5)
print(my_tuple)
mylist = list(my_tuple)
mylist.append(6)
my_tuple = tuple(mylist)
print(my_tuple)
Explanation:
This defines a tuple of 5 integers
my_tuple = (1,2,3,4,5)
This prints the tuple
print(my_tuple)
To add new element to the tuple; First, we convert it to list. This is done below
mylist = list(my_tuple)
Then, an item is appended to the list
mylist.append(6)
The list is then converted to tuple
my_tuple = tuple(mylist)
This prints the tuple
print(my_tuple)

How we ingest streaming data into Hadoop Cluster?
Hadoop could be described as an open source program to handle big data. By utilizing the MapReduce model, Hadoop distributes data across it's nodes which are a network of connected computers. This data is shared across the systems and thus enables it to handle and process a very large amount dataset at the same time. These collection of networked nodes is called the HADOOP CLUSTER.
Hadoop leverages the power and capabilities of it's distributed file system (HDFS) which can handle the reading and writing of large files from log files, databases, raw files and other forms of streaming data for processing using ingestion tools such as the apache Flume, striim and so on. The HDFS ensures the ingested data are divided into smaller subunits and distributed across systems in the cluster.

With what speed will a clock have to be moving in order to run at a rate that is one-half the rate of a clock at rest
Answer:
Speed = 0.866c
Where c is speed of light
Explanation:
We want to find the speed at which it run at a rate that is one-half the rate of a clock at rest.
Thus, we will use time dilation equation to solve it.
Thus;
t_o/√[1 - (v²/c²)] = 2t_o
Where:
t_o is time at rest
v is the speed at which it runs
c is the speed of light.
t_o will cancel out to give;
1/√[1 - (v²/c²)] = 2
Rearranging, we have;
√[1 - (v²/c²)] = ½
Let's make v the subject of the formula;
Let's square both sides to get;
1 - (v²/c²) = ½²
1 - (v²/c²) = ¼
Rearrange to get;
1 - ¼ = v²/c²
¾ = v²/c²
Take square root of both sides to get;
v/c = √¾
v = c × 0.866
v = 0.866c

Ethernet ensures that _____ on a shared network never interfere with each other and become unreadable.
Answer:
Signals.
Explanation:
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Ethernet ensures that signals on a shared network never interfere with each other and become unreadable through the use of encapsulation and standard encryption protocols.
In Computer Networking, encapsulation can be defined as the process of adding a header to a data unit received by a lower layer protocol from a higher layer protocol during data transmission. This ultimately implies that, the header (segment) of a higher layer protocol such as an application layer, is the data of a lower layer such as a transportation layer in the Transmission Control Protocol and Internet Protocol (TCP/IP).
The TCP/IP model comprises of four (4) layers;
1. Application layer: this is the fourth layer of the TCP/IP model. Here, the data unit is encapsulated into segments and sent to the transport layer.
2. Transport layer (layer 3): it receives the segment and encapsulates it into packets and sends to the internet layer.
3. Internet layer (layer 2): packets are encapsulated into frames.
4. Network layer (layer 1): frames are then converted into bits and sent across the network (LAN).
Hence, the data unit encapsulated inside a packet is known as segment, which is typically referred to as packet segmentation.
Additionally, these data, segments, packets, frames and bits transmitted across various layers are known as protocol data units (PDUs).

int fact = 1;
for(int i=2;i<=n;i++){
fact*=i;
}
return fact;
}
Explanation:
This line defines the function
public static int factorial(int n){
This declares and initializes variable fact to 1
int fact = 1;
This iterates from 2 to n
for(int i=2;i<=n;i++){
This line multiplies all integers from 1 to n
fact*=i;
}
This returns the factorial
return fact;

Which daemon manages the physical memory by moving process from physical memory to swap space when more physical memory is needed
Answer:
Swap daemon
Explanation:
Swap daemon manages the physical memory by moving process from physical memory to swap space when more physical memory is needed. The main function of the swap daemon is to monitor processes running on a computer to determine whether or not it requires to be swapped.
The physical memory of a computer system is known as random access memory (RAM).
A random access memory (RAM) can be defined as the internal hardware memory which allows data to be read and written (changed) in a computer.Basically, a random access memory (RAM) is used for temporarily storing data such as software programs, operating system (OS),machine code and working data (data in current use) so that they are easily and rapidly accessible to the central processing unit (CPU).
Additionally, RAM is a volatile memory because any data stored in it would be lost or erased once the computer is turned off. Thus, it can only retain data while the computer is turned on and as such is considered to be a short-term memory.
There are two (2) main types of random access memory (RAM) and these are;
1. Static Random Access Memory (SRAM).
2. Dynamic Random Access Memory (DRAM).

java Two smallest numbers Write a program that reads a list of integers, and outputs the two smallest integers in the list, in ascending order. The input begins with an integer indicating the number of integers that follow. You can assume that the list will have at least 2 integers and fewer than 20 integers. Ex: If the input is: 5 10 5 3 21 2 the output is: 2 and 3 To achieve the above, first read the integers into an array. Hint: Make sure to initialize the second smallest and smallest integers properly.
Answer:
The code to this question can be defined as follows:
import java.util.*;//import package for user input
public class Main //defining a class
{
public static void main(String[] args)//defining main method
{
int m1,m2,num,t,i;//defining integer variable
Scanner incx = new Scanner(System.in);//creating Scanner class object
m1 = incx.nextInt();//input value
m2 = incx.nextInt();//input value
if (m1 > m2)//use if block to check m1 greater than m2
{//swapping value
t = m1;//holding m1 value in t
m1 = m2;//defining m1 that take m2
m2 = t;//holding m2 value
}
for (i = 2; i < 6; i++)//defining for loop
{
num = incx.nextInt();//input value
if (num < m1) //defining if block to smallest value
{
m2 = m1;//holding m2 value in m1
m1 = num;//holding num value in m1
}
else if (num < m2)//defining if block to smallest value
{
m2 = num;//holding num value in m2
}
}
System.out.println(m1 + " " + m2);//print two smallest values
}
}
Output:
5
10
5
3
21
2
2 3
Explanation:
In the above code, five integer variable "m1, m2, num, t, and i" is declared, in which it creates the scanner class object for inputs the value and use m1 and m2 use to the input value.
In the next step, if a block is used to swap the value and pass into the for loop that use if block to find the two smallest values and hold its value into the m1 and m2 and print its value.
Write a Java program that asks the user to enter an array of integers in the main method. The program will ask the user for the number of integer elements to be put in the array, and then ask the user for each element of the array. The program then calls a method named isSorted() that accepts an array of integers and returns true if the list is in sorted (increasing) order and false otherwise. For example, if arrays named arr1 and arr2 store [10, 20, 30, 41, 56] and [2, 5, 3, 12, 10] respectively, the calls isSorted(arr1) and isSorted(arr2) should return true and false respectively. Assume the array has at least one integer element. A one-element array is considered to be sorted.
Answer:
The program is as follows:
import java.util.Scanner;
public class MyClass {
public static Boolean isSorted(int [] arr){
Boolean sorted = true;
for(int i = 0;i<arr.length;i++){
for(int j = i;j<arr.length;j++){
if(arr[i]>arr[j]){
sorted = false;
break;
}
}
}
return sorted;
}
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
int n;
System.out.print("Length of array: ");
n = input.nextInt();
int[] arr = new int[n];
System.out.println("Enter array elements:");
for(int i = 0; i<n;i++){
arr[i] = input.nextInt();
}
Boolean chk = isSorted(arr);
System.out.print(chk);
}
}
Explanation:
The method begins here
This line defines a method named isSorted
public static Boolean isSorted(int [] arr){
This line declares a boolean variable and initializes it to true
Boolean sorted = true;
The next two iterations iterate through elements of the array
for(int i = 0;i<arr.length;i++){
for(int j = i;j<arr.length;j++){
This compares an array element with next elements (to the right)
if(arr[i]>arr[j]){
If the next element is smaller than the previous array element, then the array is not sorted
sorted = false; The boolean variable is updated to false
break; This breaks the loop
}
}
}
This returns true or false, depending on the order of the array
return sorted;
}
The main method begins here
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
int n;
This prompts user for length of array
System.out.print("Length of array: ");
This gets length of array from user
n = input.nextInt();
This declares an array
int[] arr = new int[n];
This prompts user for array elements
System.out.println("Enter array elements:");
The following iteration gets the array elements
for(int i = 0; i<n;i++){
arr[i] = input.nextInt();
}
This calls the isSorted array
Boolean chk = isSorted(arr);
This prints true or false, depending if the array is sorted or not
System.out.print(chk);
}
Fill in this function that takes three parameters, two Strings and an int. 4- // Write some test function calls here! The Strings are the message that should be printed. You should alternate printMessage("Hi", "Karel", 5); between the Strings after each line. The int represents the total number of lines that should be printed. public void printMessage(String lineOne, String lineTwo, in For example, if you were to call 19.
printMessage("Hi", "Karel", 5);
// Start here! 12 the function should produce the following output:
Hi
Karel
Hi
Kare
Answer:
The function in Java is as follows:
public static void printMessage(String lineOne, String lineTwo, int lines){
for(int i = 1;i<=lines;i++){
if(i%2 == 1){
System.out.println(lineOne);
}
else{
System.out.println(lineTwo);
}
}
}
Explanation:
This defines the function
public static void printMessage(String lineOne, String lineTwo, int lines){
This iterates through the number of lines
for(int i = 1;i<=lines;i++){
String lineOne is printed on odd lines i.e. 1,3,5....
if(i%2 == 1){
System.out.println(lineOne);
}
String lineTwo is printed on even lines i.e. 2,4,6....
else{
System.out.println(lineTwo);
}
}
}
To call the function from main, use:
printMessage("Hi", "Karel", 5);

O >>> myDeque popleft
O >>> myDeque.clear()
O >>> my Deque pop
O >>> myDeque.clear()
Correct question:
What is the missing line?
>>> myDeque = deque('math')
>>> myDeque
deque(['m', 'a', 't'])
Answer:
myDeque.pop()
Explanation:
The double ended queue, deque found in the python collection module is very similar to a python list and can perform operations such as delete items, append and so on.
In the program written above, the missing line is the myDeque.pop() as the pop() method is used to delete items in the created list from the right end of the list. Hence, the 'h' at the right end is deleted and we have the output deque(['m', 'a', 't'])
myDeque.popleft () deletes items from the right.
