Sorting Algorithm Comparison
| Algorithm | How it Works | Complexity | Good For |
|---|---|---|---|
| Bubble Sort | Compare adjacent pairs, swap if wrong order, repeat | O(n²) | Small lists, nearly sorted data |
| Insertion Sort | Insert each element into correct position in sorted portion | O(n²) | Small lists, nearly sorted data |
| Merge Sort | Divide list in half, sort each half, merge together | O(n log n) | Large lists, guaranteed performance |
