Write a program that reads an integer and determines and prints whether it is odd or even. [Hint: Use the remainder operator. An even number is a multiple of two. Any multiple of two leaves a remainder of zero when divided by 2.].

Take input of number 12008988 in the University using appropriate data type. Write a
programme to print all the prime number digits, each in a new line. In this number
Q2: When will the ‘while’ loop be preferred over the for loop? Mention the scenario and write the
programme to demonstrate this.
class Node

public int key;
public Object data;
public Node left;
public Node right;
}
Node* search(Node root, int key)

Assignment 2
A company that wants to send data over the Internet has asked you to write a program that will encrypt the data so that it may be transmitted more securely. All the data is transmitted as four-digit integers. Your application should read a five-digit integer entered by the user and encrypt it as follows: Replace each digit with the result of adding 6 to the digit and getting the remainder after dividing the new value by 10. Then swap the first digit with the fourth, and swap the second digit with the fifth. Then print the encrypted integer.
Write a separate application that inputs an encrypted four-digit integer and decrypts it (by reversing the encryption scheme) to form the original number.
