Q1) A company wants to transmit data over the telephone lines, but they are concerned that their phones may be tapped. All their data is transmitted as four-digit integers. They have asked you to write a program that will encrypt their data so that it may be transmitted more securely. Your program should read a four-digit integer and encrypt as follows: Replace each digit by the remainder after the sum of that digit plus 7 is divided by 10. Then swap the first digit with the third, and swap the second digit with the fourth. Then print the encrypted integer. Write a separate program that inputs an encrypted four-digit integer and decrypts it to form the original number. thanks in advance for ur help.
