 Kindergarten Counting Game 

Everybody sit down in a circle. Ok. Listen to me carefully.

``Woooooo, you scwewy wabbit!''

Now, could someone tell me how many words I just said?

Input and Output

Input to your program will consist of a series of lines, each line containing multiple words (at least one). A ``word'' is defined as a consecutive sequence of letters (upper and/or lower case).

Your program should output a word count for each line of input. Each word count should be printed on a separate line.
