+ If the numbers 1 to 5 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 1 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.
