Graphs pattern
Network Delay Time
Given a directed weighted graph where each edge gives the travel time of a signal, and a starting node, return the time it takes for the signal to reach every node. If some node is unreachable, return -1. Watch it run step by step, then write your own pseudocode and get it checked by AI.
