This ensures that when all edge weights are non-negative, we will never go through the adjacency list of any vertex more than once. Removing it will cause TLE on the last test case of the above problem! phobias with l

"WebA solution tofinding the shortest path from each node to every other node also exists in the form of the Floyd-Warshall algorithm. A directed graph can be seen as a flow network, where each edge has acapacity and each edge receives a flow. The Ford-Fulkerson algorithm is used to find out themaximum flow from a source to a sink in a graph. " - Floyd warshall algorithm using adjacency list
