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.

题目要求,前边的数对后边数取余,其实只要不断取余就行了,不需要大数除法的模拟。
附代码:
#include<stdio.h> #include<string.h> char c[1100]; long i,j,k,l,m,n; int main() { while(scanf("%s%d",c,&n)!=EOF) { l=strlen(c); m=0; for(i=0;i<l;i++) { m=m*10+c[i]-'0'; m=m%n; } printf("%ld\n",m); } return 0; }
