题目链接:https://leetcode.com/problems/shortest-path-visiting-all-nodes/题意:已知一条无向图,问经过所有点的最短路径是多长,边权都为1,每个点可能经过多次。这道题写的时候想简单了,把它当成树的直径来做了,求出一条最长路径len(len上的点只经过一次),2*(点数-1)-len即为答案,竟然过了,后来看了看...
题目:Leetcode Shortest Path Visiting All Nodes You have an undirected, connected graph of n nodes labeled from 0 to n - 1. You are given an array graph where graph[i] is a list of all the nodes connected with node i by an edge. Return the length of the shortest path that visits e...
https://leetcode.com/problems/shortest-path-visiting-all-nodes/description/ An undirected, connected graph of N nodes (labeled 0, 1, 2, ..., N-1) is given as graph. graph.length = N, and j != i is in the list graph[i] exactly once, if and only if nodes i and j are connec...
847. 访问所有节点的最短路径 - 存在一个由 n 个节点组成的无向连通图,图中的节点按从 0 到 n - 1 编号。 给你一个数组 graph 表示这个图。其中,graph[i] 是一个列表,由所有与节点 i 直接相连的节点组成。 返回能够访问所有节点的最短路径的长度。你可以在任一节点开始

Return the length of the shortest path that visits every node. You may start and stop at any node, you may revisit nodes multiple times, and you may reuse edges. Example 1: Input: [[1,2,3],[0],[0],[0]] Output: 4 Explanation: One possible path is [1,0,2,0,3] ...
