Google is the king

Given a string, we would like to know how many words are in the string. We know that all the words are separated by a space ' '. How many words are there in a given string?

The input contains a single line. It might contain some whitespace at the beginning or at the end. You should ignore that.

The program should print the number of words in that line.
