WHAT ARE DATA STRUCTURES? | DIFFERENCE BETWEEN STACK AND QUEUE | NOOB CODE PRO

 INTRODUCTION:

Hello there, how is it going? I hope you are doing great. Welcome to another lesson from NCP. In this article, we will be discussing about data structures, what they mean, how to use them and some practical applications of them. Let us get started with our today’s lesson ☺.

TYPES OF DATA STRUCTURES:

A data structure is a format used to store and organize information. List, tuples, dictionaries are some data structures you are already familiar with.

Let us take a look at some of the well know data structures:

1. STACKS:

Stacks are similar to lists, like lists you can add or remove an item, but unlike lists, you can only add or remove the last item. Adding an item to a stack is called pushing and removing an item from a stack is called popping. It is a LIFO (Last In First Out) data structure which means the last added item is the first one to be removed. Whatever we put in a stack comes out in reverse order. A stack is really useful in solving problems like reversing a string. 

Let us take a look at an example, where will create a simple python program named ‘stack.py’ and create a ‘Stack’ class of our own, which can be used to create and work with stacks:

2. QUEUE:

A queue is a FIFO (First In First Out) data structure. Think of it as a line of people waiting to buy a movie ticket. The first person in line is the first one to get the ticket. Similar to stacks, queues have lists as their basic structure. Basically, the order of input is the same as the order of output.

CONCLUSION:

Both of these data structures are really useful in solving problems which includes adding or removing the first or the last element in a list. I hope you find this really helpful, if you did, dropping us a like is one way to show us some appreciation;). Share your opinion with us in the comments below.
