PROBLEM:
Chef has X liters of petrol, each of which lets him travel 15 km.
The distance between his house and DAIICT is Y km. Will he be able to travel there and back?
EXPLANATION:
Since Chef needs to travel there and back, the total distance is 2Y km.
With X liters of petrol, Chef can travel upto 15X km.
So, the answer is “Yes” if 2Y \leq 15X and “No” otherwise.
TIME COMPLEXITY
