Both methods work. Well done. You hit the learning goals here. See my notes on time complexity, but nice work!

Since .include? has to traverse the entire array it should take O(n) time, and since it's nested into a loop the method is an O(n2) algorithm.

This is actually O(m * n) where m is the number of letters in the strings.
