UVA+POJ中大数实现的题目，持续更新（JAVA实现）

import java.util.Arrays;
import java.util.Scanner;
import java.math.*;

public class Main
{
public static void main(String[] args)
{
Scanner cin = new Scanner(System.in);
BigInteger a,b;
String s;
while(cin.hasNext())
{
a=cin.nextBigInteger();
s=cin.next();
b=cin.nextBigInteger();
if(s.equals("/"))
{
System.out.println(a.divide(b));
}
else if(s.equals("%"))
{
System.out.println(a.mod(b));
}
}
cin.close();
}

}
