int_range

Arrays and matrices16

Objective

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

Steps

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);.

examples

$ int_range(3, 7)

[3, 4, 5, 6, 7]

$ int_range(-2, 1)

[-2, -1, 0, 1]

$ int_range(5, 2)

[5, 4, 3, 2]

$ int_range(0, 0)

[0]
