You can implement a stack in a few different ways.
- Linked list
Let's walk through how you can create one and the functions you would need for a stack.
First, let's start with implementing a class we'll use for our stack.
We need to be able to store data in our stack, right?
Let's use the constructor method to create and initialize our stack. We'll add a data variable that will hold elements to our stack.
Next, let's simply push data into our stack.
The next method we'll need is a pop method to remove the last element from our stack.
Now, let's add a peek function!
Let's play around with our stack now and add some data!
Here's the code if you want to play around with it.
