💡 Key Takeaways
- Compare major sorting algorithms (Quicksort, Mergesort, Heapsort) and understand their trade-offs.
- Grasp stability, in-place sorting, and memory usage to choose the right method.
- Analyze time and space complexity (best/average/worst) using Big-O for common sorts.
- Learn about non-comparison sorts (radix, counting) and when they offer advantages.
❓ Frequently Asked Questions
What is a stable sort and why does stability matter?
A stable sort preserves the relative order of equal keys. It matters when sorting by multiple fields or when chaining sorts that rely on prior order.
How do merge sort, quicksort, and heapsort differ in stability and in-place behavior?
Merge sort is stable and typically not in-place (uses extra space). Quicksort is usually in-place and not stable. Heapsort is in-place and not stable.
What is external sorting and when would you use it?
External sorting handles data too large to fit in memory, using disk-based passes (e.g., external merge sort) to produce a sorted dataset.
What is non-comparison sorting and when can it beat the O(n log n) lower bound?
Non-comparison sorts like counting sort, radix sort, and bucket sort do not rely on element comparisons and can achieve O(n) time for data with small integer keys or limited digit ranges.
What is an adaptive sort and can you name an example?
An adaptive sort takes advantage of existing order to improve performance. TimSort is a common example (used in Python and Java).
