Ok, disclaimer: I DON'T think is a good solution, but I wanted to try
it-- it IS Friday after all.
The code below creates a four-dimensional array for all the numbers and
letters in a QWERTY keyboard. It then creates a struct of all the
letters and numbers to provide a "lookup" table to quickly find what row
and position a given letter is in. Then it finds all its neighbors.
I'm pretty convinced that it would be easier and faster just to
hard-code all the combinations, but it was a fun proof of concept.
Also, I'm REALLY sorry, but I don't have CF8 on my dev box so I can't
do implicit array and struct declarations. :(
Passing in "s" to the neighbors function returns the following letters:
w,e,a,d,z,x
