From 0 to 1 Data Structures & Algorithms in Java - Build A Queue With Two Stacks

The video tutorial explains how to implement a queue using two stacks. It begins with an introduction to the behavior and functionality of queues and stacks, followed by real-life applications of queues in various systems. The tutorial then provides a detailed explanation of implementing a queue using two stacks, including visual demonstrations of enqueue and dequeue operations. Finally, it presents a code snippet and analyzes the performance of this implementation, highlighting its time complexity and efficiency.
