题目描述

There is a new attraction in Singapore Zoo: The Infinite Zoo.

The Infinite Zoo can be represented by a graph with an infinite number of vertices labeled 1,2,3,1,2,3,\ldots . There is a directed edge from vertex uu to vertex u+vu+v if and only if u&v=vu\&v=v , where &\& denotes the bitwise AND operation. There are no other edges in the graph.

Zookeeper has qq queries. In the ii -th query she will ask you if she can travel from vertex uiu_i to vertex viv_i by going through directed edges.

输入格式

The first line contains an integer qq ( 1q1051 \leq q \leq 10^5 ) — the number of queries.

The ii -th of the next qq lines will contain two integers uiu_i , viv_i ( 1ui,vi<2301 \leq u_i, v_i < 2^{30} ) — a query made by Zookeeper.

输出格式

For the ii -th of the qq queries, output "YES" in a single line if Zookeeper can travel from vertex uiu_i to vertex viv_i . Otherwise, output "NO".

You can print your answer in any case. For example, if the answer is "YES", then the output "Yes" or "yeS" will also be considered as correct answer.
