How do I return the last element of a set?

set::end() It returns an iterator pointing to past the last element of the set container.

How do I get the first element of a multiset?

What is multiset in Java?

Multiset is a collection that supports order-independent equality, like Set, but may have duplicate elements. Elements of a multiset that are equal to one another are referred to as occurrences of the same single element. The total number of occurrences of an element in a multiset is called the count of that element.

What is set and multiset in CPP?
