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 array counts as a 90° rotation in that direction.
Worked Example
["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
["left", "right", "left", "right"] ➞ 0
["right", "right", "right", "right", "right", "right", "right", "right"] ➞ 2
["left", "left", "left", "left"] ➞ 1
Notes
Return a positive number. All tests will only include the words "right" and "left".
