Let A[1::n] be an array of numbers. To find the largest number in A, one way is to divide A into two halves, recursively nd the largest number in each half, and pick the maximum between the two. (a) Write a recursive algorithm to implement the above scheme. Write a recurrence relation describing the running time of the algorithm and solve it to give a tight bound on the running time of this al- gorithm. (b) Does this recursive algorithm perform better than an incremental algorithm that computes the largest element in A by iterating through the elements of A? Explain.
