406. 根据身高重建队列 - 假设有打乱顺序的一群人站成一个队列,数组 people 表示队列中一些人的属性(不一定按顺序)。每个 people[i] = [hi, ki] 表示第 i 个人的身高为 hi ,前面 正好 有 ki 个身高大于或等于 hi 的人。 请你重新构造并返回输入数组 people 所表示的队
in the tree, you can choose any node of the tree as the root. When you select a nodexas the root, the result tree has heighth. Among all possible rooted trees, those with minimum height (i.e.min(h)) are called minimum height trees (MHTs). Return a list of all MHTs' root labe...
Solution 1: A naive solution: we choose a node as root, change the graph into a tree; we count the height of every tree node; we then calculate the minimum height taking the height of the parent tree into consideration. 1publicclassSolution {2publicclassMhtNode {3Map<Integer, Integer>chi...
According to thedefinition of tree on Wikipedia: “a tree is an undirected graph in which any two vertices are connected byexactlyone path. In other words, any connected graph without simple cycles is a tree.” The height of a rooted tree is the number of edges on the longest downward pa...
The height of a rooted tree is the number of edges on the longest downward path between the root and a leaf. 描述 对于一个具有树特征的无向图,我们可选择任何一个节点作为根。图因此可以成为树,在所有可能的树中,具有最小高度的树被称为最小高度树。给出这样的一个图,写出一个函数找到所有的最小...
Leetcode 310. Minimum Height Trees 题目: For a undirected graph with tree characteristics, we can choose any node as the root. The result graph is then a rooted tree. Among all possible rooted trees, those with minimum height are called minimum height trees (MHTs). Given such a graph, ...
(2) The height of a rooted tree is the number of edges on the longest downward path between the root and a leaf. 这道题最直接的方法就是遍历所有的节点构成来的树,然后得到最低的树,图的存储可以按照矩阵存储,或者使用Hash存储前边和后边,然后DFS遍历即可,但是超时了。 后来网上看到了一个做法,使用...
