做作业的时候,邻座的小盆友问你:“五乘以七等于多少?”你应该不失礼貌地围笑着告诉他:“五十三。”本题就要求你,对任何一对给定的正整数,倒着输出它们的乘积。

1086 就不告诉你-LMLPHP

输入格式:

输入在第一行给出两个不超过 1000 的正整数 A 和 B,其间以空格分隔。

输出格式:

在一行中倒着输出 A 和 B 的乘积。

输入样例:

5 7

输出样例:

53

C:

#include<stdio.h>
int main()
{
    int a,b,n;
    int A,count=0;
    scanf("%d %d",&a,&b);
    n=a*b;
    while(n!=0)
    {
    	A=n%10;
    	n=n/10;
    	if(A==0&&count==0)
    	{
    	    continue;
        }
        count++;
    	printf("%d",A);    
    }
	return 0;
}

C++:

#include <iostream>
using namespace std;

int main() {
    int a, b, n;
    int A, count = 0;
    cin >> a >> b;
    n = a * b;
    while (n != 0) {
        A = n % 10;
        n = n / 10;
        if (A == 0 && count == 0) {
            continue;
        }
        count++;
        cout << A;
    }
    return 0;
}

Java:

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int a = scanner.nextInt();
        int b = scanner.nextInt();
        int n = a * b;
        int A, count = 0;
        while (n != 0) {
            A = n % 10;
            n = n / 10;
            if (A == 0 && count == 0) {
                continue;
            }
            count++;
            System.out.print(A);
        }
    }
}

Python:

a, b = map(int, input().split())
n = a * b
count = 0

while n != 0:
    A = n % 10
    n = n // 10
    if A == 0 and count == 0:
        continue
    count += 1
    print(A, end='')
