Spin Around, Touch the Ground

Given a list of directions to spin, "left" or "right", return an integer of how many full 360° rotations were made. Note that each word in the list counts as a 90° rotation in that direction.

Worked Example

spin_around(["right", "right", "right", "right", "left", "right"]) ➞ 1
# You spun right 4 times (90 * 4 = 360)
# You spun left once (360 - 90 = 270)
# But you spun right once more to make a full rotation (270 + 90 = 360)

Examples

spin_around(["left", "right", "left", "right"]) ➞ 0

spin_around(["right", "right", "right", "right", "right", "right", "right", "right"]) ➞ 2

spin_around(["left", "left", "left", "left"]) ➞ 1

Notes

• Return a positive number.
• All tests will only include the words "right" and "left".
