Fuel Efficiency Evaluator

You are given the distance traveled by a vehicle (in kilometers) and the fuel used (in liters). The fuel efficiency is computed using the formula \(\frac{distance}{fuelUsed}\). Based on the calculated fuel efficiency:

• If \(15 \leq \frac{distance}{fuelUsed} \leq 25\), the vehicle is considered Efficient.
• If \(\frac{distance}{fuelUsed} < 15\), it is considered Inefficient.
• If \(\frac{distance}{fuelUsed} > 25\), it is considered Over Efficient.

Your task is to implement a program that reads input from stdin and outputs the corresponding result to stdout.

inputFormat

The input consists of a single line containing two space-separated floating-point numbers: the distance traveled (in kilometers) and the fuel used (in liters).

outputFormat

Output a single string: either "Efficient", "Inefficient", or "Over Efficient" based on the computed fuel efficiency.## sample
