# Have the function LetterCountI(str) take the str parameter being passed and
# return the first word with the greatest number of repeated letters. For
# example: "Today, is the greatest day ever!" should return greatest because it
# has 2 e's (and 2 t's) and it comes before ever which also has 2 e's. If there
# are no words with repeating letters return -1. Words will be separated by
# spaces.
