Please help me with this Algorithm problem.

Write a recursive algorithm in a pseudo code, Min-Max, for finding both the minimum and the maximum elements in an array A of n elements. Your algorithm should return a pair (a, b) where a is the minimum element and b is the maximum element.

Algorithm Min-Max(A, n)

Input: an Array A of n elements

Output: a pair of (a, b) where a is the minimum element and b is the maximum element.
