Data Structures
Data structures are like containers that help organize and store information. Imagine you have a collection of toys. You can keep them in a toy box or in the case of books, you can arrange them on a bookshelf. These toy boxes or shelves are like data structures that hold and organize the toys and books.
There are some basic data structures that are explained below:
Arrays
Arrays are like a list of items, just like a row of toys on a shelf. Each item has a specific position or index. You can add, remove, or access items using their index. Arrays are great for organizing and working with a collection of similar things.
Lists
Lists are similar to arrays, but they give you more flexibility. You can add or remove items easily, and the items don’t have to be in a specific order. Think of it as a shopping list where you can add or remove items as you, please.
Stacks
Stacks are like a pile of books, where you can only add or remove the topmost book. This is known as the Last-In-First-Out (LIFO) principle. Imagine stacking books on your desk and removing the top book each time you need one.
Queues
Queues are like waiting in line for something, such as waiting for your turn on a swing. It follows the First-In-First-Out (FIFO) principle. The person who joins the line first gets to go first. Similarly, the first item added to a queue is the first one to be removed.
Linked Lists
Linked lists are like a chain of objects connected together. Each object contains a value and a reference to the next object in the chain. You can add or remove objects easily in a linked list, and they don’t have to be stored in contiguous memory locations like arrays.
