There N is network nodes, labelled 1 to N .Given times , a list of travel times as directed edges times[i] = (u, v, w) , where are the u source node, is the v target node, and Is the time w it takes for a signal to travel from source to target.Now, we send a signal from a certain node K . How long would it take for all nodes to receive the signal? If It is impossible, return -1 .Note: N'll is in the range [1, 100] . K'll is in the range [
