(25 points) Suppose you are given an array A of length n that contains the integers 1,2,..., n, arranged in some unknown order, and that you want to find an integer a) Give a deterministic algorithm for solving this problem. What is the worst-case b) Give a randomized algorithm for solving this problem. What is the worst- i such that Al Vi. run-time complexity of your algorithm? case expected run-time complexity of your algorithm? (Formally prove your answer)
