Description

First calculate the sum of two positive integers a and b, then determine if the sum is a palindrome number.
Palindrome number: Let n be any natural number. If the natural number n₁ obtained by reversing the digits of n is equal to n, then n is called a palindrome number. For example, 121 is a palindrome number, while 123 is not.

Input Format

A single line containing two positive integers a, b ($1≤a,b≤100$) separated by a space.

Output Format

Output two lines: the first line contains a positive integer sum, representing the sum of a and b.
If sum is a palindrome number, output "Yes" on the second line; otherwise, output "No". Do not include quotes in the output.
