## 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 YESyesyeS, and Yes are all considered the same.

• 1≤�≤1000
• 1≤�≤�≤106

Output

4
5 3
1 1
4 1
2 1

YES
YES
NO
YES

### 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.
