What Is Bubble Sort?

What is Bubble Sort? A Clear and Concise Definition

Welcome to our “DEFINITIONS” category, where we delve into the world of technology, providing clear and concise explanations for common terms. Today, we’re going to unravel the mystery behind Bubble Sort, a fundamental sorting algorithm used in computer science. If you’ve ever wondered how sorting works and how algorithms come into play, you’re in the right place. Let’s dive in!

Bubble Sort, as the name suggests, works by repeatedly “bubbling” the largest (or smallest, depending on the sorting order) elements to the end of the list. It’s like sorting a deck of cards by repeatedly comparing and swapping adjacent pairs until the entire deck is sorted.

Here’s a step-by-step breakdown of how Bubble Sort works:

1. Start at the beginning of the list.
2. Compare the first and second elements.
3. If they are in the wrong order, swap them.
4. Move to the next pair of elements and repeat steps 2 and 3.
5. Continue until you reach the end of the list.
6. Repeat the above steps for the remaining adjacent pairs, ignoring the already sorted elements.
7. Keep repeating until the entire list is sorted.

Let’s illustrate the process with a simple example:

Consider the list [4, 7, 2, 1, 5]. Applying Bubble Sort, we would perform the following swaps:

1. Comparing 4 and 7: [4, 7, 2, 1, 5] -> [4, 2, 7, 1, 5]
2. Comparing 7 and 2: [4, 2, 7, 1, 5] -> [4, 2, 1, 7, 5]
3. Comparing 7 and 1: [4, 2, 1, 7, 5] -> [4, 2, 1, 5, 7]
4. Comparing 7 and 5: [4, 2, 1, 5, 7] (already sorted)
5. Comparing 4 and 2: [4, 2, 1, 5, 7] -> [2, 4, 1, 5, 7]
6. Comparing 4 and 1: [2, 4, 1, 5, 7] -> [2, 1, 4, 5, 7]
7. Comparing 4 and 5: [2, 1, 4, 5, 7] (already sorted)
8. Comparing 2 and 1: [2, 1, 4, 5, 7] -> [1, 2, 4, 5, 7]
9. Comparing 2 and 4: [1, 2, 4, 5, 7] (already sorted)
10. Comparing 4 and 5: [1, 2, 4, 5, 7] (already sorted)
11. Comparing 5 and 7: [1, 2, 4, 5, 7] (already sorted)

After all the necessary swaps, the list becomes [1, 2, 4, 5, 7]. Now, it’s sorted in ascending order using Bubble Sort!

While Bubble Sort is conceptually easy to understand and implement, it has one major drawback – its inefficiency. The algorithm has a time complexity of O(n^2), meaning it becomes slower as the number of elements increases. For larger lists, there are far more efficient sorting algorithms available.

Key Takeaways:

• Bubble Sort is a simple and inefficient sorting algorithm.
• It repeatedly compares adjacent elements in a list and swaps them if they are in the wrong order.

Now that you have a clear understanding of what Bubble Sort is, you can appreciate both its simplicity and its limitations. If you ever come across the term “Bubble Sort” in the world of computer science, you’ll now know exactly what it entails.
