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...
An undirected, connected graph of N nodes (labeled0, 1, 2, ..., N-1) is given asgraph. graph.length = N, andj != iis in the listgraph[i]exactly once, if and only if nodesiandjare connected. Return the length of the shortest path that visits every node. You may start and st...
You are given an undirected graph with weighted edges. The length of some path between two vertices is the bitwise xor of weights of all edges belonging to this path (if some edge is traversed more than once, then it is included in bitwise xor the same number of times). You have to ...
Given a undirected weighted graph, consisting of n vertices and m edges. The task is to find all the edges that are a part of every shortest path from vertex 1 to vertex n. In another word, find all the edges that if we delete it from the original graph, the shortest path from vert...
