Can you explain the stability of merge sort in C++?
Sure! Merge sort is a stable sorting algorithm, meaning that it preserves the relative order of equal elements.
How does merge sort achieve stability?
It achieves stability by merging equal elements in the order they appear in the original array during the merge process.
Are there any scenarios where merge sort might not be stable?
In its basic implementation, merge sort is stable. However, if you modify the merge process or use a different data structure, it could become unstable.
Can you show me a code example of stable merge sort in C++?
Certainly! Here's a simple implementation of stable merge sort in C++ that maintains the order of equal elements.
