When to Use Insertion Sort

✓Small datasets (≤ 50 elements)
✓Nearly sorted or partially sorted data
✓Online sorting (sorting data as it arrives)
✓When stability is required
✗Large datasets (poor worst-case performance)

Real-world Applications

•Hybrid sorting in advanced algorithms (like Timsort)
•Real-time data processing systems
•Sorting small subarrays in divide-and-conquer algorithms
•Playing cards sorting (most natural way humans sort)
