“Woooooo, you scwewy wabbit!”

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

現在，有人能告訴我我剛剛說了多少字?

Input

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).

程式的輸入將包含好幾行，每行包含多個單字（至少一個單字）。“單字”被定義為一連串的字母（大小寫均可）。

Output

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

你的程式應該對每行輸入輸出單字的數量。每筆輸出都應該印在單獨一行上。

Hint

The spacing between words may be other symbols or numbers.
