🔍 Search
One-line summary: Locate a target within a collection — from O(n) linear scans to O(log n) binary search on sorted data.
Algorithms in this section
Runnable implementations (with tests) live alongside this guide in this folder:
- Linear Search — O(n), works on unsorted data
- Binary Search — O(log n), requires sorted input
- Jump Search — O(√n), sorted input, block jumps
- Interpolation Search — O(log log n) average on uniformly distributed sorted data
Quick Comparison
| Algorithm | Time (avg) | Requires Sorted? |
|---|---|---|
| Linear Search | O(n) | No |
| Binary Search | O(log n) | Yes |
| Jump Search | O(√n) | Yes |
| Interpolation Search | O(log log n) | Yes (uniform) |
