Solution: Most Stones Removed with Same Row or Column

Explore the Union Find approach to solve the problem of removing the maximum number of stones that share the same row or column. Learn to group stones through connected components and apply efficient union and find operations to achieve an optimized solution with near-linear time complexity.

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] ...
