[Solution] Expert Setter CodeChef Solution

Problem

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

Munchy submitted $X$ problems for approval. If $Y$ 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 $T$, denoting the number of test cases.
• Each test case consists of a two space-separated integers $X$ and $Y$ - 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.

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 $3$: 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.
