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) 解决的问题 查找无向图是否成环 在无向图上,查询是否在同一个连通图中 思想 利用数组建树,数组元素值代表该位置的父亲结点,如果为数组元素值为本身代表为独立结点 找祖先 每次询问自己的父亲,直到查找到数组元素值为本身的点即为祖先。
