Bubble Sort: A Simple Sorting Algorithm

What is Bubble Sort?

Can you explain how Bubble Sort works?

Answer:

Bubble Sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order.

Bubble Sort is a basic sorting algorithm that works by repeatedly stepping through the list of elements to be sorted, comparing each pair of adjacent items and swapping them if they are in the wrong order. The pass through the list is repeated until no swaps are needed, indicating that the list is sorted.

For example, let's say we have an array [5, 3, 8, 2, 1]. The Bubble Sort algorithm would start by comparing 5 and 3. Since 5 is greater than 3, they would be swapped to get [3, 5, 8, 2, 1]. The algorithm would then move to the next pair, 5 and 8, which are already in the correct order. This process continues until the list is fully sorted: [1, 2, 3, 5, 8].

Bubble Sort is not the most efficient sorting algorithm, especially for large data sets, as it has a time complexity of O(n^2). However, it is easy to understand and implement, making it a good choice for educational purposes or small data sets.
