In python

In order to play Wordle, we need to first know the list of valid words $($i$.$e$.$ the dictio$-$

nary$).$ If we know the dictionary we are playing with, then we know what words are

valid guesses to make, and we also know that the answer must be one of the words in

it$.$

Therefore, to get us started, write a program that takes as input a number of words

$($one on each line$),$ stores the words for later use, and then outputs the total size of the

dictionary.

Input

Input consists of a series of five letter words, one per line. Each word is written in

uppercase. The end of the dictionary is indicated by the string ## which should not be

included in the dictionary. The dictionary is guaranteed to contain at least one word.

Output

Output the size of the dictionary we are playing with.
