Solution: Most Stones Removed with Same Row or Column

Explore how to apply the union find algorithm to solve the problem of removing the maximum number of stones that share the same row or column. Learn to group stones into connected components and compute the maximum removable count efficiently with union and find operations.

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] represents the ith ...
