Problem

A problem setter is called an expert if at least 50% of their problems are approved by Chef.

Munchy submitted � problems for approval. If � problems out of those were approved, find whether Munchy is an expert or not.

Input Format

  • The first line of input will contain a single integer �, denoting the number of test cases.
  • Each test case consists of a two space-separated integers � and � - the number of problems submitted and the number of problems that were approved by Chef.

Output Format

For each test case, output on a new line YES, if Munchy is an expert. Otherwise, print NO.

The output is case-insensitive. Thus, the strings YES, yes, yeS, and Yes are all considered the same.

Constraints

  • 1≤�≤1000
  • 1≤�≤�≤106

Explanation:

Test case 1: We are given that 3 out of 5 problems were approved. Thus, 60% of the problems were approved. Since at least 50% of the problems were approved, Munchy is an expert.

Test case 2: We are given that 1 out of 1 problems were approved. Thus, 100% of the problems were approved. Since at least 50% of the problems were approved, Munchy is an expert.

Test case 3: We are given that 1 out of 4 problems were approved. Thus, 25% of the problems were approved. Since at least 50% of the problems were not approved, Munchy is not an expert.

Test case 4: We are given that 1 out of 2 problems were approved. Thus, 50% of the problems were approved. Since at least 50% of the problems were approved, Munchy is an expert.
