You must write a program that can both decrypt and encrypt a single word that is entered by the
user. The initial choice of encryption and decryption is left up to the user. Additionally, the user will enter a value to be utilized when determining how to translate the character.
Decryption: Convert all characters in the word by utilizing the discovered map index
Having trouble with the decryption portion:
¦ Given a character in the word, determine its index in the map string
¦ Add the position to the first character in range of valid characters for a word
? This is the position of the character in the alphabet!
? What is the range of valid characters? Check the validation step. What is the first character in that range?
