Learn the basics of sorting algorithms with a step-by-step guide to implementing Bubble Sort in Python.
Introduction to Bubble Sort
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. The pass through the list is repeated until the list is sorted.
Step 1: Understanding the Algorithm
The Bubble Sort algorithm works by repeatedly swapping the adjacent elements if they are in the wrong order.
Step 2: Implementing the Algorithm in Python
def bubble_sort(arr):
n = len(arr)
for i in range(n):
for j in range(0, n - i - 1):
if arr[j] > arr[j + 1] :
arr[j], arr[j + 1] = arr[j + 1], arr[j]
return arr
## Step 3: Testing the Algorithm
```python
arr = [64, 34, 25, 12, 22, 11, 90]
print("Original array:", arr)
print("Sorted array:", bubble_sort(arr))
Output
Original array: [64, 34, 25, 12, 22, 11, 90]
Sorted array: [11, 12, 22, 25, 34, 64, 90]
Conclusion
In this tutorial, we learned the basics of the Bubble Sort algorithm and implemented it in Python. This is a beginner-friendly algorithm and is a good starting point for learning more complex sorting algorithms.
