229,204 PointsThose are the set combining operators:
- | = Union — all items from both sets
- & = Intersect — items in common to both sets
- - = Difference — items from first set that are not in the second set
- ^ = Symmetric Difference — items from both sets not in the other (opposite of intersect)
