in thread Challenge: 8 Letters, Most Words
This certainly doesn't look like brute force to me.
First you get the words each letter appears in (regardless of how many times it appears). Then, you consider the top 8 letters based on how many words contain the letter but only allow each letter to appear once.
Your solution would probably be a lot faster if you also threw out any word from the dictionary that had repeated letter since I can't see how you would ever consider them.
