What is bubble sort in programming?

What is sorting:

The arranging of information is quite possibly the most essential, yet significant issue in software engineering. Arranging structures is an extraordinary contextual investigation for the individuals who need to learn Data Structures and Algorithms.

What is bubble sort:

Bubble sort in C is a sorting algorithm in which we repeatedly traverse the array and exchange unordered adjacent items. We repeat this until the matrix is ​​sorted.

As an example, for the array mentioned above - [5, 1, 4, 2, 3] we can see that 5 should not be on the left of 1 and so, we swap them to get: [1, 5, 4, 2, 3]. Next, we see that 5 should again not be on the left of 4. We swap 5 and 4 to get [1, 4, 5, 2, 3]. We repeat this for 5 and 2 and subsequently for 5 and 3 to get [1, 4, 2, 3, 5].

As can be seen - after one “pass” over the array, the largest element (5 in this case) has reached its correct position - extreme right. Let us try to repeat this process.

(1, 4) is correct. However, (4, 2) is in the incorrect order. Therefore, we swap 4 and 2 to get [1, 2, 4, 3, 5]. Now again, (4, 3) is incorrect so we do another swap and get [1, 2, 3, 4, 5].

As can be seen, the array is sorted!

This exactly is how bubble sort in C works.
