# 17.  Number letter counts

# If the numbers 11 to 55 are written out in words: one, two, three, four, five, then there are 3+3+5+4+4=19 letters used in total.

# If all the numbers from 11 to 1000 (one thousand) inclusive were written out in words, how many letters would be used?

# NOTE: Do not count spaces or hyphens. For example, 342 (three hundred and forty-two) contains 23 letters and 115(one hundred and fifteen) contains 20 letters. 
# The use of "and" when writing out numbers is in compliance with British usage.
