Sorting Algorithms: A Complete Comparison


Sorting Algorithms: A Complete Comparison


Sorting is one of the most fundamental operations in computer science. Let's compare the most common sorting algorithms.


Bubble Sort


Simple but inefficient, O(n²) time complexity. Best for educational purposes.


Merge Sort


Divide and conquer approach with O(n log n) time complexity. Stable and consistent performance.


Quick Sort


Also divide and conquer, O(n log n) average case but O(n²) worst case. Very fast in practice.


Choosing the Right Algorithm


  • Small datasets: Insertion sort
  • General purpose: Quick sort or merge sort
  • Stable sort needed: Merge sort
  • In-place sorting: Quick sort or heap sort
