mirror_sequence

Language/Type: Python recursion

Write a recursive function named mirror_sequence that accepts an integer parameter n and prints a sequence of n numbers as in the table below. For odd numbers the sequence has a single 1 in the middle, while for even values it has two 1s in the middle. Throw a ValueError if passed a value less than 1.

Call Output
mirror_sequence(1) 1
mirror_sequence(2) 1 1
mirror_sequence(3) 2 1 2
mirror_sequence(4) 2 1 1 2
mirror_sequence(5) 3 2 1 2 3
mirror_sequence(6) 3 2 1 1 2 3
mirror_sequence(7) 4 3 2 1 2 3 4
mirror_sequence(8) 4 3 2 1 1 2 3 4
mirror_sequence(9) 5 4 3 2 1 2 3 4 5
mirror_sequence(10) 5 4 3 2 1 1 2 3 4 5
