Input file contains several blocks of input. 
Each block is terminated by a line containing a 
#
as its first character. You should not consider
this line within the block. 
There is no space at the end of a line. You may assume 
each word 
#
as ``I'm'' and ``You've'', and hyphenated words 
are treated as one word. For example, ``you've'' is a one-
letter word. Hyphenation may occur across two lines.
