JAVA大数模板

遇到高精度怎么办？用几十行的C/CPP!？显然不是最佳选择。

此时用JAVA就能轻松解决：

import java.math.BigDecimal;
import java.util.Scanner;
import java.math.BigInteger; 

public class Main
{
    public static void main(String args[]){
        BigInteger a[] = new BigInteger[110];
        BigInteger b[] = new BigInteger[110];
        Scanner cin = new Scanner(System.in);
        int n;
        n = cin.nextInt();
        for (int i=1;i<=n;i++)
        {
            a[i] = cin.nextBigInteger();
            b[i] = cin.nextBigInteger();
            System.out.println(a[i].add(b[i]));
            System.out.println(a[i].subtract(b[i]);
        }
    }
}
