Complete Modern C++ - std::deque

This video tutorial explains the concept of a deque (double-ended queue), highlighting its similarities and differences with a vector. The deque allows efficient addition and removal of elements from both ends and supports random access. However, it is not ideal for insertion and deletion except at the ends. The video demonstrates how to use a deque in code, including adding elements to both ends and accessing elements using the subscript operator. It also covers functions like push_front, pop_back, and pop_front. An example is provided to illustrate the deque's functionality, showing the output after modifying elements.
