Solution: Most Stones Removed with Same Row or Column

Understand how to apply the union find pattern to group stones sharing rows or columns and find the maximum number of stones that can be removed. Explore the algorithm's union and find operations, and learn to optimize the solution for efficient performance on large inputs.

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] ...
