Problem 4: (4 2 points) Consider the following algorithm for finding the largest number in an arrav. function MyMax(array A[1.n) if n = 1 then return A1 end if B empty array for i from 1 to [n / 2] do append max(A21-11, ) to B end for if n is odd then append A[n] 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
