I would also try to break up your requirements into smaller pieces. For
example, some things to solve:
How would you get input?
How would you break up a string into individual characters?
How would you break up an encoded string into individual numbers?
How would you put the characters/numbers back together for output?
Have you started writing any code? What have you tried so far?
