❓ Frequently Asked Questions
What is sorting and why is it used?
Sorting arranges items in a specified order (e.g., ascending). It enables faster searches, easier data analysis, and consistent data presentation.
What is the difference between stable and unstable sorting?
Stable sorting preserves the relative order of equal elements; unstable sorting may reorder them. Stability matters when prior ordering by another key must be kept.
Which sorting algorithms are typically fast on average, and when should you choose them?
QuickSort and MergeSort are common fast options (≈ O(n log n) on average). QuickSort is fast but pivot-dependent; MergeSort is stable and reliable, though it may use extra space.
What does 'in-place' sorting mean, and which algorithms sort in place?
In-place sorting uses little or no extra space beyond the input. QuickSort and HeapSort are in-place; MergeSort can be in-place with special implementations but typically uses extra space.
