Implementing Bubble Sort

Implementing Bubble Sort

Introduction

This tutorial will guide you through implementing the bubble sort algorithm to sort an array of numbers.

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 Outer Loop

We will initialize an outer loop that iterates through the array.

Step 3: Initialize the Inner Loop

We will initialize an inner loop that iterates through the unsorted portion of the array.

Step 4: Compare Adjacent Elements

We will compare adjacent elements and swap them if they are in the wrong order.

Step 5: Repeat Steps 3 and 4 Until the Array is Sorted

We will repeat steps 3 and 4 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 to implement the bubble sort algorithm to sort an array of numbers.
