Problem 4: (4 + 2 points) Consider the following algorithm for finding the largest number in an array. function MYMax(array Al1.n]) B empty array for i from 1 to [n /2 do append max(A[2i - 1], A[2i]) to B end for if n is odd then append Aln] to B end if return MyMax(B) end function Find a -expression for the number of operations performed by the algorithm in terms of n
