In your code, you prep your translation hash %m with keys from the input alphabet, and values of a through z. What if the input alphabet was [a..z1]
, or [a..z0-9]
? These are more than 26 characters and thus, the 27th and higher characters will have null values for their keys, and will mess up your tr-and-back transformation.
