reserve函数 atoi函数

• reserve函数可以实现字符串的反转 非常简单实用
• atoi函数可以实现把数字的字符串转换为 整数类型
  两个函数经常放一块使用 能简化很多操作

You are given numbers a and b. Calculate the sum of a and reverse of b. A reverse of a number is a number which contains the same digits in reverse order. For example, reverse of 230 is 32, and reverse of 0 is 0.

Input
The input contains two integers a and b (0 ≤ a, b ≤ 109), separated by a single space. The numbers are given without leading zeros.

Output
Output the sum of a and reverse of b.

Examples
Input
5 15
Output
