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.
Sample Input
Meep Meep! I tot I taw a putty tat. I did! I did! I did taw a putty tat. Shsssssssssh ... I am hunting wabbits. Heh Heh Heh Heh ...
Sample Output
