Implement the recursive function int ordered_pairs(int al], int size). This function returns true if the array is made ordered pairs and false otherwise (you can assume that the array size is even and >= 2). An ordered pair is a pair of elements where the first is less than or equal to the second. For example, 1 and 2 is an ordered pair, 1 and 1 is an ordered pair, but 2 and 1 is not an ordered pair. Examples: [1. 1, 2. 2, 0, 0, 3, 3, -1, -1] true [1. 1, 1. 2, 1. 3, 0, 9, 3. 5] true [1. 3, 0. 1, 5, 2, 2, 2, 2. 2] false ok ok You are allowed to add more arguments to the function besides the array and its size if you need it.
