PROBLEM:
Out of N members present in Chefland’s parliament, X of them voted for a resolution and the others voted against it.
The resolution is passed if half or more of the members voted for it.
Is the resolution passed?
EXPLANATION:
Use an if condition to check whether the condition is true, and print Yes or No appropriately.
As for the condition itself, we want to check whether X is at least half of N.
This is true only when 2X \geq N, so check for that.
TIME COMPLEXITY
\mathcal{O}(1) per test case.
CODE:
Editorialist's code (Python)
for _ in range(int(input())):
n, x = map(int, input().split())
print('Yes' if 2*x >= n else 'No')
