Problem Description
As we know, Big Number is always troublesome. But it's really important in our ACM. And today, your task is to write a program to calculate A mod B.

To make the problem easier, I promise that B will be smaller than 100000.

Is it too hard? No, I work it out in 10 minutes, and my program contains less than 25 lines.
 

Input
The input contains several test cases. Each test case consists of two positive integers A and B. The length of A will not exceed 1000, and B will be smaller than 100000. Process to the end of file.
 

Output
For each test case, you have to ouput the result of A mod B.

Sample Output
  
2 5 1521
 
 
#include<stdio.h> #include<string.h> int mod(char *n1,int n2) {   int temp,i;   int k=strlen(n1);       temp=0;   for(i=0;i<k;i++)   {     temp=temp*10+(n1[i]-'0');     temp%=n2;   }      return temp; } int main() {     int n,;     char str[10000];     while(~scanf("%s %d*c",str,&n))     {        printf("%d\n",mod(str,n));                                 } return 0;    }
