int_range

Your mission

Write a function that allocates an integer array covering every value between two bounds, in the direction they imply.

See it in action

int_range(3, 7)

Expected result

[3, 4, 5, 6, 7]

Your checklist

For your own tracking. Tests grade your code.

Allocate the array on the heap using malloc. The caller is responsible for freeing it.
The array must contain every integer from from to to, both inclusive.
When from is less than or equal to to, values must appear in ascending order.
When from is greater than to, values must appear in descending order.
The prototype is int *int_range(int from, int to);.

More examples

int_range(-2, 1)

Expected result

[-2, -1, 0, 1]

int_range(5, 2)

Expected result

[5, 4, 3, 2]

int_range(0, 0)

Expected result
