Problem: Last Stone Weight

Explore how to implement a max heap in C# using PriorityQueue to solve the Last Stone Weight problem. Learn to repeatedly select the two heaviest stones, smash them, and handle reinsertions until one or no stones remain. Understand the algorithm's time and space complexity for efficient coding.

We'll cover the following...

Statement

You are given an integer array stones, where each element stones[i] represents the weight of the ithi^{th} stone.

A game is played with these stones. In each turn, the two heaviest stones are selected and smashed together. Let the weights of these two stones be x and y, where x ≤\leq y. The outcome of the smash is as follows:

  • If x == y, both stones are completely destroyed.

  • If x ≠\neq ...
