代码

使用Scanner会运行超时

package hello;
import java.math.BigInteger;
import java.util.Scanner;
public class Hello {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        BigInteger b1 = input.nextBigInteger();
        BigInteger b2 = input.nextBigInteger();
        System.out.println(b1.divide(b2) + " " + b1.remainder(b2));
    }
}

使用BufferedReader则没有问题，中间两个try都是eclipse自己生成的

import java.util.Scanner;
import java.math.*;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Main {
    public static void main(String[] args) throws IOException {
        // TODO Auto-generated method stub
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
        String[] ab = null;
        try {
            ab = bufferedReader.readLine().split(" ");
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        try {
            bufferedReader.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        BigInteger a = new BigInteger(ab[0]);
        BigInteger b = new BigInteger(ab[1]);
        BigInteger result[] = a.divideAndRemainder(b);
        System.out.println(result[0] + " " + result[1]);
    }
}
