You are given a network of n nodes, labeled from 1 to n.You are also given times, a list of travel times as directed edges times[i] = (u i, v i, w i), where u i is the source node, v i is the target node, and w i is the time it takes for a signal to travel from source to target.. We will send a signal from a given node k.Return the minimum time it takes for all the n nodes to receive the signal. If you just replace Java code "prices.length-1" with C++ code "prices.size()-1", you will fail in the empty testcase. You can assign values to the proper char in the same for loop where you from right to left. a little bit explanation about the 4th solution: Let's assume left,right,leftMax,rightMax are in positions shown in the graph below. In the previous approach, the set function is efficient, but in the get function we iterate linearly over the time range. So, 0-1 will not be interpreted as -1 but 2^32-1. we can see height[left] < height[right],then for pointerleft, he knows a taller bar exists on his right side, then if leftMax is taller than him, he can contain some water for sure(in our case).So we go ans += (left_max - Apply NOW.
