Queues - Interview Questions | Lecture 58 | C++ and DSA Foundation Course

In this video, Sanket sir will provide a comprehensive overview of Queues in C++. The video will start by introducing the concept of Deque (double-ended queue), which allows for elements to be inserted and deleted from both ends. The video will then move onto some important problems related to the relationship between Queues and Stacks. Finally, in the video we will discuss Circular Queues, which are used in scenarios where there is a fixed amount of space available, and elements need to be continually added and removed. Sanket sir will provide a step-by-step walkthrough of each concept, complete with relatable examples and code snippets to help us understand how Queues work in practice. By the end of the video, we will have a solid understanding of Queues in C++ and how they can be used in various programming scenarios.
