set

When you think about data structures, one of the first things that comes to mind is how we manage collections of items.

In C++, the Standard Template Library (STL) provides a powerful container called set that helps you manage a collection of unique elements efficiently. It's not just about storing data; it's about doing it in a way that allows for fast lookups, insertions, and deletions.

Imagine you have a large collection of names, and you want to ensure there are no duplicates. How do you handle that?

A set is your answer! It handles uniqueness automatically and provides operations that are both fast and intuitive.
