Structures made simple
We break down complex data structures using everyday objects, helping you visualize how memory works before you write a single line of code.
Think of an array as a numbered egg carton. Each slot holds one item, and you can access any egg instantly if you know its index number.
A linked list is like a scavenger hunt. Each clue points to the next location. You must follow the path to find the specific item you need.
A stack works like a tray dispenser. You add a tray to the top and take from the top. The last one added is the first one removed.
