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...)
Write a function called eval, which takes a string and returns a boolean. This string is allowed 6 different characters: 0, 1, &, |, (, and ). Eval should evaluate the string as a boolean expression, where 0 is false, 1 is true, & is an and, and | is an or. An example string might look like "(0 | (1 | 0)) & (1 & ((1 | 0) & 0))"
