In word search puzzles you get a square of letters and have to find specific words in them.
For example:
jefblpepre
camdcimgtc
oivokprjsm
pbwasqroua
rixilelhrs
wolcqlirpc
screeaumgr
alxhpburyi
jalaycalmp
clojurermt
There are several programming languages hidden in the above square.
Words can be hidden in all kinds of directions: left-to-right, right-to-left, vertical and diagonal.
Given a puzzle and a list of words return the location of the first and last letter of each word.
