I tried to implement union find (disjoint set data structure) algorithm in C++. There I used unordered_map data structure. Is there a better way of doing this using any other data structure. While finding the root I have used the following way. int root(int i){ if(i != parent[i])...

并查集: (union-find sets)是一种简单的用 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。一般采取树形结构来存储并查集,并利用一个rank数组来存储集合的深度下界,在查找操作时进 行路径压缩使后续的查找操作加速。这样优化实现的并查集,空间复杂度为O(N),建立一...
UVA 11987 Almost Union-Find (并查集) 题意: 这里有N个数编号1 ~N,开始每个数各自在一个集合里面,然后有三种命令: 1 P Q :把 P 所在的集合和 Q 所在的集合合并,如果已经在一个集合里面了就忽视 2 P Q : 把 P 这个元素从它所在的集合里面拿出来放到 Q 里面,,如果已经在一个集合里面了就忽视...

The union is at least as big as necessary to hold its largest data member, but is usually not larger. The other data members are intended to be allocated in the same bytes as part of that largest member. The details of that allocation are implementation-defined, except that all non-static...

Here, we find the union of l1 and l2 using the + operator and select only unique elements using the set() function and then finally convert the set into a list using the list() function. Get Union of More than Two Lists in Python We have already computed the union of the two lists...
