Problem Description

Each year on May the graduate students are busy writing thesis, and the graduation thesis needs thousands of words. It's not a simple matter. Counting the words correctly become an interesting job.

We all know that the thesis may include English words, numbers, punctuation marks, images, formulas, and so on.

During the word count, we assume that English words, a string of meaningful numbers and punctuation mark is valid statistics word.

The single character in English words or numbers can not be counted as a word.

For example, the word "acm" count as one word instead of three words, number "2011" counted as a word. Of course, such space and carriage returns(Enter) can't be considered a word.

Write a program to help graduates to test whether the number of words under the thesis requirement.

Input

There are multiple test case in input, each test case end with a single line "###", the input may contain english character, numbers, punctuation e.g. ':' , ',' , '+' , '-', and space, Enter.

Output

Output the number of word for each test case, and a separate line for each case.

Sample Input

A simple test

    這個題目要注意的是，單個的標點符號算做一個單詞。

     A simple+-.ui test.    答案是：8   （simple+-.ui：simple  +  -  .  ui 共5個）
