做作业的时候，邻座的小盆友问你：“五乘以七等于多少？”你应该不失礼貌地微笑着告诉他：“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。

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：

编程语言：Python

解题思想：

1.从字符串末尾开始往前拼接

2.判断特例情况

时间复杂度：O(N)

代码如下：

Number1, Number2 = map(int, input().split())
Product = Number1 * Number2
ContrastProduct = ""
 
for i in range(len(str(Product)) - 1, -1, -1):  # 从末尾开始拼接字符串
    ContrastProduct += str(Product)[i]
print(int(ContrastProduct))  # 使用int处理特例情况，100*100 = 10000，倒过来应该是1，而不是00001

}{Be very careful about how you’re treating your mascara brush. Don’t simply thrust it through the bottle opening when in use. This will only add oxygen to your bottle, which can hurt your brush. This action could increase the chance of bacterial growth. You can coat the brush by moving the container slightly.
