The relationship between collections

Use the equality operator (= =) to determine whether two sets contain all the same values.

Use The IsSubsetOf (_:) method is used to determine whether a value in a collection is also contained in another collection.

use issupersetof (_:) method to determine that a collection contains all of the values in another collection.

• Use Isstrictsubsetof (_:) or isstrictsupersetof (_:) method to determine whether a collection is a subset of another collection, or a parent collection, and the two sets are not merged equally.
• Use The Isdisjointwith (_:) method determines whether two sets do not contain the same value (whether there is no intersection).
