Problem

You are given two positive integers. Write a program that determines whether the first number is greater than the second.

Input

The input consists of several test cases. Each test case is given on a single line as two integers, each between $1$ and $1{,}000{,}000$ inclusive. The last line contains two 0s; this line is not processed.

Output

For each test case, print Yes if the first number is greater than the second, and No otherwise, one result per line.
