2.Set Difference“A组数据相对B组数据求差集”(A有B没有/A-B) 【输入】Set A - 查找数列A; Set B - 比较数列B(与A比较找不同的数据列表); 【输出】Union - A有B没有的数据。 3.Set Difference(s)“两组数据互相求差集” (A有B没有orB有A没有) 【输入】Set A - 输入数列A; Set B - 输入...
并查集(Disjoint set或者Union-find set)是一种树型的数据结构,常用于处理一些不相交集合(Disjoint Sets)的合并及查询问题。 2、 基本操作 并查集是一种非常简单的数据结构,它主要涉及两个基本操作,分别为: A. 合并两个不相交集合 B. 判断两个元素是否属于同一个集合 (1) 合并两个不相交集合(Union(x,y)) ...
s.unionSets(3,7); s.unionSets(8,1); assert(s.findSet(1) == s.findSet(6));// 1 and 6 are connected.assert(s.findSet(3) != s.findSet(6));// 3 and 6 are not connected.assert(s.findSet(1) == s.findSet(1));// 1 and 1 are connected.assert(s.findSet(3) == s....

l并查集:(union-find sets) 一种简单的用途广泛的集合. 并查集是若干个不相交集合,能够实现较快的合并和判断元素所在集合的操作,应用很多,如其求无向图的连通分量个数等。最完美的应用当属:实现Kruskar算法求最小生成树。 l并查集的精髓(即它的三种操作,结合实现代码模板进行理解): ...
p-selective setmitotic setThis paper is motivated by the open question whether the union of two disjoint NP-complete sets always is NP-complete. We discover that such unions retain much of the complexity of their single components. More precisely, they are complete with respect to more general...
In this article, we will learn about the union-find algorithm, its implementation, advantages disadvantages, and applications in detail. Let us first understand what a disjoint set is. What is the Union-Find Algorithm? The union-find algorithm is a powerful tool in computer science used to ...
8. Disjoint Sets If two sets X and Y do not have any common elements, and their intersection results in zero(0), then set X and Y are called disjoint sets. It can be represented as;, X ∩ Y = 0. Union, Intersection, Difference, and Complement of Sets ...
