A Map in C++ is an Associative Container provided by the Standard Template Library (STL). It stores elements as key-value pairs. In Map key-value pairs are ordered by their keys. This ordering is typically implemented using a self-balancing binary search tree, like a Red-Black tree, which ensures efficient access to elements based on their keys.

Welcome to a tutorial series on Map in C++. This series will be divided into 10 parts, beginning with the fundamentals and gradually progressing to explore more advanced topics and practical use cases.
