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.

Examples

flip_bool(true) ➞ 0

flip_bool(false) ➞ 1

flip_bool(1) ➞ 0

flip_bool(0) ➞ 1
