Tarjan’s off-line lowest common ancestors algorithm 之间的其他关系。并查集的实现有两种[7],quick-find 以及quick-union,较为常用的方法是基于quick-union ,而 quick-union 有两个维度的改进,&ldquo... LCA中的 union 操作,是在处理完一个节点时,将其与已经处理
3.p = find(3.p) -- find(4) x==3 4 我们假定p为指向父节点的值。那么如上面所描述,每次求一个节点的父节点值的时候就需要递归到下一层,比如这里求1.p,就需要求find(2),这样一直到find(4)。我们知道find(4)返回的结果是4。于是按照递归返回的关系就可以知道3.p = find(4),于是得到find(3)的...

比你的 Rust 更快”的结论也是来自这个打赌。他的故事或许可以说明运行策略在研发实践中的重要性。
Today’s lecture: Union-Find What problem are we solving? –What is the abstract problem? The dynamic equivalence problem How do we represent the concepts? How do we solve the problem? –What is the algorithm? How efficient is our solution?
🎭 PsuendoCode Union Find Algorithm Pattern ♾ ⏰: O(V * logV) 🪐: O function find(int[] parent, i) { if (parent[i] == -1) return i; return find(parent, parent[i]); function union(int[] parent, x, y) { xset = find(parent, x); yset = find(parent, y); parent...
I reversed the query, broke down the path s — e to s — LCA(s,e) — e, and used this algorithm to paint the tree. (root_val[s] : value of edge s — parent(s), dep[s] = depth of s. nxt[s] = parent(s)) intpaint(ints,inte,intx){if(dep[s]<=dep[e])returns;if(...
