Write a Python script that consists of a single function definition: a function named cubes_mod_n that accepts a single integer n (assumed to be positive). The function returns a sorted list (from least to greatest) consisting of the cubes mod n, without repeats. If the integer 4 were passed in to the function, the list returned would be equal to [0, 1, 3]. If the integer 12 were passed in to the function, the list returned would be equal to [0, 1, 3, 4, 5, 7, 8, 9, 11]. If the integer 14 were passed in to the function, the list returned would be equal to [0, 1, 6, 7, 8, 13]. (The cubes mod n are the integers m satisfying 0 m
