题目描述

Initially you have a single pile with nn gold nuggets. In an operation you can do the following:

  • Take any pile and split it into two piles, so that one of the resulting piles has exactly twice as many gold nuggets as the other. (All piles should have an integer number of nuggets.)

    One possible move is to take a pile of size 66 and split it into piles of sizes 22 and 44 , which is valid since 44 is twice as large as 22 .

Can you make a pile with exactly mm gold nuggets using zero or more operations?

输入格式

The first line contains an integer tt ( 1t10001 \leq t \leq 1000 ) — the number of test cases.

The only line of each test case contains two integers nn and mm ( 1n,m1071 \leq n, m \leq 10^7 ) — the starting and target pile sizes, respectively.

输出格式

For each test case, output "YES" if you can make a pile of size exactly mm , and "NO" otherwise.

You can output the answer in any case (for example, the strings "yEs", "yes", "Yes" and "YES" will be recognized as a positive answer).

说明/提示

The first test case is pictured in the statement. We can make a pile of size 44 .

In the second test case, we can perform the following operations: {9}{6,3}{4,2,3}\{\color{red}{9}\} \to \{\color{red}{6},3\} \to \{4,2,3\} . The pile that is split apart is colored red before each operation.

In the third test case, we can't perform a single operation.

In the fourth test case, we can't end up with a larger pile than we started with.
