Sorting is a fundamental operation in computer science, and one of the simplest and most widely used sorting algorithms is Bubble Sort. In this article, we will explore what Bubble Sort is, how it works, and provide an example to help you understand it better.

## What is Bubble Sort?

Bubble Sort is a comparison-based sorting algorithm that repeatedly compares adjacent elements and swaps them if they are in the wrong order. The algorithm gets its name from the way smaller elements “bubble” to the top of the list during each iteration.

## How does Bubble Sort work?

To understand how Bubble Sort works, let’s break down its steps:

**Step 1:**Compare the first two elements of the list.**Step 2:**If the first element is greater than the second element, swap them.**Step 3:**Move to the next pair of adjacent elements and repeat steps 1 and 2.**Step 4:**Continue iterating through the list until no more swaps are needed.

This process is repeated for each element in the list until it is completely sorted. The algorithm guarantees that after each iteration, at least one element will be in its correct position at the end of the list.

## An Example

To illustrate how Bubble Sort works, let’s consider an array of numbers: [5, 3, 8, 4, 2]. We will walk through each step of the algorithm:

**First iteration:**- [
__5__,__3__, 8, 4, 2] - [
**3**,**5**, 8, 4, 2] (swapped) **Second iteration:**- [3,
__5__,__8__, 4, 2] - [3,
**5**,**8**, 4, 2] (swapped) **Third iteration:**- [3, 5,
__8__,__4__, 2] - [3, 5,
**4**,**8**, 2] (swapped) **Fourth iteration:**- [3, 5, 4,
__8__,< u >2]

< li > [3 ,5 ,4 ,< b >2 ,< b >8 ]( swapped )

< / ul >< / ol >

< p >

After the fourth iteration,

the list is sorted and we have our final result: [2,3,

4,

5,

8].< / p >< h2 >

Conclusion < / h2 >

< p >

Bubble Sort may not be the most efficient sorting algorithm, especially for large lists, but it is simple to understand and implement. It serves as a good starting point for learning about sorting algorithms and their principles.Remember, understanding different sorting algorithms can be valuable in various programming scenarios.
