What are the main differences between Quick Sort and Merge Sort in C++?
Quick Sort is generally faster and uses less memory, while Merge Sort is stable and works better for large datasets.
Can you explain the time complexity of both algorithms?
Sure! Quick Sort has an average time complexity of O(n log n) but can degrade to O(n²) in the worst case. Merge Sort consistently runs in O(n log n).
Which one should I use for sorting a large array?
If stability is important, go with Merge Sort. If performance is key and you can handle the worst-case scenario, Quick Sort is preferable.
Are there any specific scenarios where Quick Sort performs better?
Yes, Quick Sort performs better on average for in-memory sorting of large datasets, especially when the pivot is chosen wisely.
