Understanding the Bubble Sort Algorithm

Introduction

This tutorial will guide you through understanding the bubble sort algorithm and how to implement it in Python.

Step 1: Define the Problem

We are given an array of numbers and we need to sort it in ascending order.

Step 2: Initialize the Array

We will initialize the array with some unsorted numbers.

Step 3: Iterate Through the Array

We will iterate through the array and compare each pair of adjacent elements.

Step 4: Swap the Elements

If the elements are in the wrong order, we will swap them.

Step 5: Repeat the Process

We will repeat the process until the array is sorted.

Example Code

def bubble_sort(array):
    n = len(array)
    for i in range(n):
        for j in range(0, n - i - 1):
            if array[j] > array[j + 1] :
                array[j], array[j + 1] = array[j + 1], array[j]
    return array
print(bubble_sort([64, 34, 25, 12, 22, 11, 90]))  # Output: [11, 12, 22, 25, 34, 64, 90]

Conclusion

In this tutorial, we learned how the bubble sort algorithm works and how to implement it in Python.
