Solution: Most Stones Removed with Same Row or Column
Understand how to apply the Union Find pattern to solve the problem of removing the maximum number of stones on a 2D plane that share rows or columns. Learn to group stones into connected components, optimize removals, and grasp the step-by-step algorithm including union and find operations with explanations on time and space complexity.
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 ...
