Provide a set of positive integers (an array of integers). Each integer represent number of nights user request on Airbnb.com. If you are a host, you need to design and implement an algorithm to find out the maximum number a nights you can accommodate. The constrain is that you have to reserve at least one day between each request, so that you have time to clean the room. Example: 1) Input: [1, 2, 3] ===> output: 4, because you will pick 1 and 3 2) input: [5, 1, 2, 6] ===> output: 11, because you will pick 5 and 6 3) input: [5, 1, 2, 6, 20, 2] ===> output: 27, because you will pick 5, 2, 20

The question was the following. I'm rephrasing the question to make it clear for everyone to understand: - You are going on a one-way flight trip that includes billions of layovers. - You have 1 ticket for each part of your trip (i.e: if your trip is from city A to city C with a layover in city B, then you will have 1 flight ticket from city A to city B, and 1 flight ticket from city B to city C. - Each layover is unique. You are not stopping twice in the same city. - You forgot the original departure city. - You forgot the final destination city. - All the tickets you have are randomly sorted. Question are: - Design an algorithm to reconstruct your trip with minimum complexity. - How would you improve your algorithm. Example: - randomly sorted: New York->London San Francisco-> Hong Kong Paris->New York London->San Francisco - sorted: Paris->New York New York->London London->San Francisco San Francisco-> Hong Kong
