代码(Code) 初始化: cpp for (int i = 1; i <= n; i ++ ) fa[i] = i; // 初始时,每个元素都互不相关,在自己的集合中 for (int i = 1; i <= n; i ++ ) r[i] = 1; // 按秩合并 找祖宗节点 + 路径压缩: cpp int find(int x) { if (x == fa[x]) return x : fa[x]...
并查集(Disjoint-Set)是一种可以动态维护若干个不重叠的集合,并支持合并与查询两种操作的一种数据结构。 模板题目 原题链接 题目描述 一共有n个数,编号是1∼n,最开始每个数各自在一个集合中。 现在要进行m个操作,操作共有两种: M a b,将编号为a和b的两个数所在的集合合并,如果两个数已经在同一个集合中...

Following are the time complexities of disjoint set operations: Find(x):O(log n) where n is the number of elements. Union(x, y):O(log n) where n is the number of elements. MakeSet(x):O(1) Following are the applications of disjoint set data structure: ...
Here 2 different subsets are {A, B, C} and {D, E}. You have to perform two operations here : Union (A, B) - connect two elements A and B. Find (A, B) - find, is there any path connecting two elements A and B Example: You have a set of elements S = {0, 1, 2, 3,...
So something I failed to mention (or remember to do myself) on your previous PR: we have a set of quickcheck property tests, which check a bunch of invariants that should apply to type relations, using randomly-generated types. These don't run in CI (because they are inherently slow and...
