Coding a Dijkstra is not hard. %70 of my time spent on tackling TLE, as my last post. Dijkstra works in BFS manner, but at each step, it picks the shortest child greedily and then relax all other neighbors. Data Structure: since there could be up to…

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 connected. Return the length of the shortest path that visits…
