Thought Process

I'm going to imagine there is a word with 20 letters and they are all z's, the word value of this number would be 520, it would be the 23rd triangle number, so I generate a list containing the first 23 triangle numbers.

From Problem 22 I use the same function to find the word value of a name. I simply go through the list with all the names, find the word value and see if it is in the triangle numbers list.
