Use C++ or Python to Encrypt using Feistel cipher (one round only) with a key of the size of 5 which is [1,1,0,1,1]

Use message: The password is 3074 in reverse minus 25

Write a program that uses brute force attack on the encryption to get to the plaintext.

This means that your encryption program will use the given key, but your decryption program will use all permutations of the size 5 key (5! = 120 different possibilities). I NEED both the encryption as well as the decryption program. The decryption program should permute all values in the key.
