A number is left-heavy if the digits on the left side are larger than the digits on the right. It is right-heavy if the digits on the right side are larger than the digits on the left. Else, it is balanced.
Create a function that takes in an integer and classifies it into one of the three mutually exclusive categories: left, right or balanced. For inputs with an odd number of integers, ignore the fulcrum (the middle number).
seesaw(3449) ➞ "right"
# since 34 < 49
seesaw(1143113) ➞ "left"
# since 114 > 113 (3 is the fulcrum)
seesaw(585585) ➞ "balanced"
# since 585 == 585
If input is None return "balanced".
