range_desc

Your mission

Write a function that allocates and returns an array containing every integer from max down to min, inclusive.

See it in action

range_desc(1, 4)

Expected result

[4, 3, 2, 1]

Your checklist

For your own tracking. Tests grade your code.

Use malloc to allocate the array, the caller is responsible for freeing it.
The array must have exactly |max - min| + 1 elements.
Index 0 holds max; the final index holds min.
Each successive element decreases by 1.
The prototype is int *range_desc(int min, int max);.

Expected result

range_desc(5, 5)

Expected result
