Given a list with an odd number of elements, return whether the scale will tip "left" or "right" based on the sum of the numbers. The scale will tip on the direction of the largest total. If both sides are equal, return "balanced".
scale_tip([0, 0, "I", 1, 1]) ➞ "right"
# 0 < 2 so it will tip right
scale_tip([1, 2, 3, "I", 4, 0, 0]) ➞ "left"
# 6 > 4 so it will tip left
scale_tip([5, 5, 5, 0, "I", 10, 2, 2, 1]) ➞ "balanced"
# 15 = 15 so it will stay balanced
