from collections import Counter
from typing import Tuple
def follow(instructions: str) -> Tuple[int]:
count = Counter(instructions)
return (count['r'] - count['l'], count['f'] - count['b'])
if __name__ == '__main__':
print("Example:")
print(follow("fflff"))
# These "asserts" are used for self-checking and not for an auto-testing
assert follow("fflff") == (-1, 4)
assert follow("ffrff") == (1, 4)
assert follow("fblr") == (0, 0)
print("Coding complete? Click 'Check' to earn cool rewards!")
