A company wants to transmit data over the Internet but isconcerned about the security of the sensitive data. All of the dataare transmitted as four-digit integers. The company asked you towrite a program that encrypts the data so that it can betransmitted securely. Your program should read a four-digit integerand encrypt it as follows: Replace each digit (the sum of thatdigit plus 7) modulus 10. Then, swap the first digit with thethird, swap the second with the fourth and print the encryptedinteger. Add decryption functionality to your program above thatinputs an encrypted four-digit integer
