Binary Search: Iterative vs Recursive
Updated Apr 28, 2026
Short answer
Iterative uses a loop; Recursive calls itself with updated boundaries.
Deep explanation
Searching is a fundamental operation in computer science. Iterative uses a loop; Recursive calls itself with updated boundaries. Linear search is reliable for small or unsorted datasets, while Binary search scales much better for large, ordered data.
Real-world example
Looking for a specific name in a randomly ordered list of names.
Common mistakes
- Trying to use Binary Search on an unsorted array.
