这里有一篇十分精彩、生动的 并查集详解 (转); “朋友的朋友就是朋友”⇒ 传递性,建立连通关系disjointset,并查集(一种集合),也叫不相交集,同时也是一种树型的数据结构;用于处理一些不相交集合(DisjointSets)的合并(merge)及查询(find)问题。常常在使用中以森林来表示。集就是让每个元素构成一个单元素的集合,也...

并查集(Union-find Sets)是一种非常精巧而实用的数据结构,它主要用于处理一些不相交集合的合并问题。一些常见的用途有求连通子图、求最小生成树的 Kruskal 算法和求最近公共祖先(Least Common Ancestors, LCA)等。 使用并查集时,首先会存在一组不相交的动态集合S={S1,S2,⋯,Sk}S={S1,S2,⋯,Sk},一般都会使...
In the below input graph, We have two components and thus two disjoint sets. Those are, Now, how we can find the disjoint sets. Here comes the find(X) & UNION (X,Y) ADT operation. The operation finds the set name and here we use array for that. We use a paren...
