Please solve part four of question 1 asap.

Problem 1. Write the following computer programs to simulate a mini data encryption system (MDES). Since it is just a simulation, the bit and the binary strings in the following can be expressed as integers 0 and 1. 4. Suppose the plaintext is "how do you like computer science" and the key is {101101010010100101101011). Use the above programs to compute the ciphertext. The ciphertext is written in English letters (from the correspondence described in 1.). Problem 1. Write the following computer programs to simulate a mini data encryption system (MDES).
