Cloned from https://bitbucket.org/behindthebuttons/6letterwordexercise/
There's a file in the root of the repository, input.txt, that contains words of varying lengths (1 to 6 characters).
Your objective is to show all combinations of those words that together form a word of 6 characters. That combination must also be present in input.txt
E.g.:
foobar
fo
obar
should result in the ouput:
fo+obar=foobar
You can start by only supporting combinations of two words and improve the algorithm at the end of the exercise to support any combinations, if time permits.
Treat this exercise as if you were writing production code; think TDD, SOLID, clean code and avoid primitive obsession. Be mindful of changing requirements like a different maximum combination length, or a different source of the input data.
Don't spend too much time on this; an hour or so is fine.
When starting this exercise, please make a fork of this repository.
