- [Instructor] Welcome to another video lesson. This time, we'll be talking about stacks and how to use them in C++. A stack is a container that follows the last in, first out principle for storing elements. This means that only the element most recently added can be accessed first. In other words, when we want to retrieve a specific element from the stack, we must remove all elements that were added before it. Most stacks operate with three main operations, push, pop, and top. Push adds an element to the top of the stack, pop removes the element at the top, and the top operation returns the top element without removing it. Stacks are often used when we need to store and access multiple pieces of data in a specific order. They have various practical applications, such as call stacks in programming and undo/redo operations in software. In the following example, we'll rely on the stack data structure provided in the…
