Grind 75 problem 8 - Word Break (Failed attempt)
NOTE: I had the problem flipped. This solution below assumes I need to complete all the dictionary words with the string. I actually need to complete the string using any or all of the words in the dictionary. My solution works to solve the problem I had in mind, but it doesn't work to solve the actual problem. I am keeping this for posterity, but will restart this problem in a new post.
