Due to a programming concept known as truthiness, certain values can be evaluated to (i.e. take the place of) booleans. For example, 1 (or any number other than 0) is often equivalent to True, and 0 is often equivalent to False.
Create a function that returns the opposite of the given boolean, as a number.
flip_bool(True) ➞ 0
flip_bool(False) ➞ 1
flip_bool(1) ➞ 0
flip_bool(0) ➞ 1
