SDUT中大数实现的题目，持续更新（JAVA实现）

SDUT2525：A-B (模板题）

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

public class Main
{

    public static void main(String[] args)
    {
        Scanner ci = new Scanner(System.in);
        BigInteger a;
        BigInteger b;
        while(ci.hasNext())
        {
            a=ci.nextBigInteger();
            b=ci.nextBigInteger();
            System.out.println(a.subtract(b));
        }
        ci.close();
    }

}

SDUT3134：大数取模

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

public class Main

    public static void main(String[] args)
    {
        Scanner cin = new Scanner(System.in);
        while(cin.hasNext())
        {
            BigInteger a,b;
            a=cin.nextBigInteger();
            b=cin.nextBigInteger();
            System.out.println(a.mod(b));
            
        }
        cin.close();
    }
