My code is for the purpose of running through a wordlist and seeing what words it can make from the user input.

The problem I'm running into is if, say, the user types in "ball" the program will output "a", "all", and "ball" but will skip over words like "lab" because it's not in order in the world "ball".

I'm confused as to how I can solve this problem can anyone offer advice?
