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

#include<math.h>
using namespace std;
char a[9999];
int main()
{
    int f=1;

    while(gets(a))
    {
        int len=strlen(a);
        int count=0;
        for(int i=0; i<len; i++)
        {
            if(isalpha(a[i]))
                f=1;
            else
            {
                if(f)
                count++;
                f=0;
            }
        }
        printf("%d\n",count);
    }
    return 0;
}
