Concept
Bubble sort is a simple comparison sorting algorithm that repeatedly swaps adjacent elements when they are in the wrong order.
Computer Science DSA Lab
Bubble Sort Visualizer for Interactive DSA Practice
Watch bubble sort compare neighboring values, swap them when needed, and move larger values toward the end of the array. Learn the concept, operation flow, complexity, and real-world use cases through a focused OpenLabs interactive visualizer.
DSA Visualizer
Comparison sorting
Best: O(n), Average: O(n^2), Worst: O(n^2), Space: O(1)
Step 1
Compare neighbors
Step 2
Swap if needed
Step 3
Finish pass
Step 4
Grow sorted region
Operation flow
Each pass pushes the largest remaining value toward its final position, forming a sorted region at the end of the array.
Complexity
Best: O(n), Average: O(n^2), Worst: O(n^2), Space: O(1)
Visualization
Watch each operation update the structure or algorithm state step by step.

Bubble Sort FAQs
What is bubble sort?
Bubble sort repeatedly compares adjacent elements and swaps them until the array is sorted.
What is bubble sort time complexity?
Bubble sort is O(n^2) on average and worst case, with O(n) best case when optimized for an already sorted array.
Is bubble sort good for large datasets?
No. Bubble sort is mainly used for learning because it is simple but inefficient for large datasets.
