Replacement encryption
Write a function that receives a string and return the encrypted value according to the algorithm below. Then write a function that receives the encryption phrase and returns the initial string.
In this encryption:
Each verse must be replaced by its mirror in the alphabet. For example the letter A must be replaced with Z
Attention to uppercase and lowercase letters are important
Example:
Input: abcdEfghijklmnopqrsstuvwxyz
Encrypted phrase: zyxwvutsrqponmlkjihgfedcba
