Most Stones Removed with Same Row or Column
Explore how to apply the union-find algorithm to remove the maximum number of stones from a 2D plane, where stones can be removed if sharing the same row or column with another stone. This lesson helps you understand the problem constraints, assess stone positions, and implement an efficient solution using union-find.

Statement
Given an array of 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 , where ...
