1. Given an array that contains duplicates (except for one value), find the one value that does not have a duplicate in that array. Explain the complexity of your algorithm. So in the array: A = [2, 3, 4, 5, 2, 3, 4] your algorithm should return 5 since that's the value that does not have a duplicate. 2. Explain the process that happens when you type your username and hit submit on a website (HTTP, server/client communication, etc...)
