Solution: Network Delay Time
Understand how to determine the minimum time required for a signal to reach all nodes in a network graph. Learn to implement Dijkstra’s algorithm using an adjacency dictionary and priority queue to optimize signal delay calculations. This lesson helps you evaluate unreachable nodes and compute network delay efficiently.
