<p>A disjoint set data structure (also called union find or merge find set) is a data structure that tracks a set of elements partitioned into a number of disjoint (non-overlapping) subsets. Some situations where disjoint sets can be used are- to find connected components of a graph, kruskal's algorithm for finding <a class="el" href="../../d4/d12/namespace_minimum.html" title="Implementation of Minimum Edit Distance algorithm.">Minimum</a> Spanning Tree etc. There are two operation which we perform on disjoint sets - 1) Union 2) Find </p>
