Bubble Sort
Explore the recursive technique behind Bubble Sort through a step-by-step explanation and C++ implementation. Learn how this simple sorting algorithm swaps adjacent elements, and how recursion simplifies sorting by fixing the largest elements successively. Understand its unoptimized O(n²) time complexity and discover a potential optimization to stop early when the array is sorted.
We'll cover the following...
R## Problem statement
Given an array arr, you need to sort the elements.
Solution: Recursive approach
Bubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in the wrong order.
Let’s look at the visualization first so we can understand how Bubble Sort works.
Now that we have understood the process of Bubble Sort, we can move ahead to the ...
