Most Stones Removed with Same Row or Column

Explore how to apply the Union Find pattern to efficiently solve the problem of maximizing the number of stones removed from a 2D plane based on shared rows or columns. Understand the problem constraints, use graph connectivity concepts, and implement your solution to manage stone removal strategically within the given conditions.

Statement

Given an array of nn stones in a two-dimensional plane, where each stone is represented by a pair of x and y coordinates, find the maximum number of stones we can remove with the following condition:

A stone can be removed if it shares either the same row or the same column with another stone that has not been removed so far.

Stones are provided as an array, stones, of length nn, where stones[i]=[xi,yi]stones[i] = [x_i, y_i] ...
