Hints: - Remember that Imp commands need to be enclosed in <{...}> brackets. - Remember that the assignment rule works best when it's applied "back to front," from the postcondition to the precondition. So your proof will want to start at the end and work back to the beginning of your program. - Remember that [eapply] is your friend.) *) Definition swap_program : com (* REPLACE THIS LINE WITH ":= _your_definition_ ." *).

Problem 1.Write computer programs for the Substitution Cipher based on Z29 which is corresponding to 26 alphabetic characters (0 - 25), space (26), and “, ” (27) “.”(28).The key is a random permutation π on Z29. Write down encryption and decryptionprograms. For the encryption, the plaintext and the key need to be input. To inputthe key, use the permutation of 0, 1, . . . , 28. The plaintext should be input as Englishletters. The out put will be the ciphertext which is also English letters. Select aparagraph of text which contains more than 25 words (I don’t think any two peoplewill choose a same paragraph if they choose independently) and encrypt it using yourencryption algorithm. Then use your decryption program to check the correctness.You can use Java. Record your plaintext, ciphertext and the key π in your answer sheet.
