That's fine of course, we just get a lot of "do my homework for me" type questions here. The code works (at least on my machine) and as far as I can tell from your descriptions in this thread it generates the output you're looking for, so feel free to just use it. The learning curve of this particular code may be a little steep, and it contains a lot of benchmarking/statistics code which of course you don't need, but at least the theory behind a Trie is still something you can look into if you like. Doing a linear search on a long word list is inefficient when run often (which doesn't seem to be the case in your situation) so the size/speed tradeoff of a trie can be very useful.
