Learn how to implement the bubble sort algorithm to sort an array of integers.

Introduction to Bubble Sort

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

Step 1: Define the Problem and the Approach

We are given an array of integers and we need to sort it in ascending order. We will use the bubble sort algorithm to solve this problem.

Step 2: Initialize the Array

We will initialize the array with some unsorted integers.

array = [64, 34, 25, 12, 22, 11, 90]

Step 3: Loop Through the Array and Compare Adjacent Elements

We will loop through the array and compare each pair of adjacent elements. If the elements are in the wrong order, we will swap them.

for i in range(len(array)):
    for j in range(len(array) - 1):
        if array[j] > array[j + 1]:
            array[j], array[j + 1] = array[j + 1], array[j]

Step 4: Print the Sorted Array

Finally, we will print the sorted array.

print(array)

Example Use Case

Here's an example use case:

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