Write a function to find the longest common prefix string amongst an array of strings. Given a string queryIP, return "IPv4" if IP is a valid IPv4 address, "IPv6" if IP is a valid IPv6 address or "Neither" if IP is not a correct IP of any type.. A valid IPv4 address is an IP in the form "x 1.x 2.x 3.x 4 " where 0 <= x i <= 255 and x i cannot contain leading zeros.

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. In the previous approach, the set function is efficient, but in the get function we iterate linearly over the time range. For every power of 2 I will take the largest 2^i which costs me 1 unit and gives me a lot of 2's. shiv1305 created at: October 10, 2022 7:03 AM | Last Reply: user0705A 2 days ago. Description.
