Symmetric difference set: The symmetric difference set of set A and set B is defined as the set of all elements in set A and set B that do not belong to A∩B, denoted as A△B, that is, A△B={x|x∈ A∪B, x∉A∩B}, ie A△B=(A∪B)—(A∩B). That is, A△B=(A—B)∪(B—A)

Obviously, the symmetric difference set operation satisfies the commutative law: A△B=B△A, and the symmetric difference set is also called symmetric difference.

Usage example

Collection (A): 1, 2, 3

Collection (B): 2, 3, 4
