Maximum Points After Enemy Battles

Explore how to apply greedy algorithms to solve the problem of maximizing points in a game scenario where you manage energy to defeat enemies. Understand strategies to optimally perform operations that either consume or restore energy, helping you gain the highest possible points. This lesson enhances your ability to tackle similar coding interview problems effectively.

We'll cover the following...

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 00 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 11.

  • Your energy decreases: currentEnergy = currentEnergy - ...
