In this video we will learn how to use std set in cpp programming language, and few important points to remember are as follows :
1. std::set is an Associative Container that contains a sorted set of unique objects of type Key.
2. It is usually implemented using Red-Black Tree.
3. Insertion, Removal, Search have logarithmic complexity.
4. If we want to store user defined data type in set then we will have to provide
compare function so that set can store them in sorted order.
5. We can pass the order of sorting while constructing set object.

BOTTOM LINE:
It store unique elements and they are stored in sorted order (A/D)
