Greetings, aspiring coders! Today, we're going to delve deep into the complexities of data structures, specifically the std::set from the C++ Standard Template Library (STL), and explore how to handle queries efficiently. This is a common problem, often encountered in numerous data science and algorithmic problems. So let's gear up to unravel the mysteries of std::set operations and get our hands dirty with some interactive problem-solving!

Before delving into the task, let's understand what a std::set is and why we would use it. std::set is a data structure in the C++ STL that stores unique elements while maintaining sorted order.

Advantages of using std::set:

1. Extracting minimum (using *set.begin()) or maximum (using *(--set.end())) values will be a constant time operation, i.e., $O(1)$ as they are always at the start or end of the set.
