随机录入两个整数，被除数与除数（都是正数且不超过int范围）将两数相除，要求不适用乘法、除法和%运算

package test;
import java.util.Scanner;
public class test1{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        System.out.println("输入被除数与除数：");
        int a = sc.nextInt();
        int b = sc.nextInt();

        //定义商数为n
        int n = 0;
        while(a >= b){
            a = a - b;
            n++;
        }
        System.out.println("商为：" + n);
        System.out.println("余数为：" + a);
    }
}
