Explore the full potential of C++ by mastering the standard library.

Become a C++ Programmer

The C++ standard library is a collection of all the tools and utilities available in C++. It received its latest update in 2017, known as C++17. The update introduces many new features that further optimize our code. This module will help us fully grasp C++ and use it to its full potential.

C++ Standard Library

## Problem statement

Use `std::unordered_set` instead of `std::unordered_map` and `std::unordered_multiset` instead of `std::unordered_multimap` in the program.
* `std::set`, `std::multiset`, and all variations are only degenerated versions of `std::map` and `std::multimap`, missing the associated value.
