HackerRank - Queue Using Two Stacks | Full Solution with Examples and Visuals | Study Algorithms смотреть онлайн

You are required to replicate the operations of a queue, using only the provided two stack data structures. The implemented could should support functions like enqueue, dequeue, head, and isEmpty. Watch this video to see a live demo of how this solution can be implemented. You don't have different ways to implement this but you can come up with a solution with intuition. Watch the video to understand the problem in a simplified manner. I then work along with you to solve it in an efficient manner. All along with visuals and explanations.
