complement operator

In logic and mathematics, the complement operator refers to taking the opposite or "not" of a certain set or condition. For example, if you have a group of objects that are red, the complement would be all objects that are not red. Similarly, in Boolean logic, if a statement is true, its complement is false, and vice versa. It's a way of expressing everything outside a particular set or condition, effectively flipping or negating the original idea to cover what’s absent or different.
