Print What It Returns

cube(n: int) -> int is already written and returns the number multiplied by itself three times. Complete show_cube(n: int) -> None so it calls cube with its parameter and prints the value that comes back; the result only appears on screen if something prints it, because a return value by itself is silent. The driver reads one integer and calls show_cube; leave the driver as it is. Input: one line, an integer, no prompt. Output: the cube on one line.
