First of my AWS project at hand~ I feel so happy to work with a great team! Thanks Vicky, Kyle and Dishi~ During the whole process, my responsibility is to build a connection from AWS to Google Bigquery. Here is my solution~

A hard question similar to 'Min Rewards'. 'peaks and valley' technique is not working properly in this coding challenge, because it contains the same values next to each other. Traverse left-to-right and right-to-right is a better option.

A hard question solved in 15 minutes. Use 'peaks and valley' technique to solve this question. But there are still something to improve.
