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

只要两个单词以非字母字符隔开，就算两个单词。

", cnt）;}return 0;}
