Statement

You are given an integer array enemyEnergies where each element represents the energy value of an enemy, and an integer currentEnergy representing your initial energy.

You start with $0$ points, and all enemies are initially unmarked. You may perform either of the following operations any number of times to accumulate points:

Operation 1 — Choose an unmarked enemy i such that currentEnergy >= enemyEnergies[i]:

Your points increase by $1$ .
Your energy decreases: currentEnergy = currentEnergy - ...
