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 Input
2 312 7152455856554521 3250
 

Sample Output
251521

前面的数对后面的数取余




AC代码:
#include<iostream>#include<cstring>using namespace std;char str[1100];int main(){long m,n,i,j;while(cin>>str){cin>>n;j=strlen(str);m=0;for(i=0;i<j;i++){m=m*10+str[i]-'0';m%=n; }cout<<m<<endl;}return 0;}#include<iostream>#include<cstring>using namespace std;char str[1100];int main(){long m,n,i,j;while(cin>>str){cin>>n;j=strlen(str);m=0;for(i=0;i<j;i++){m=m*10+str[i]-'0';m%=n; }cout<<m<<endl;}return 0;}
