What are the applications of stable sorting in C++11?

Stable sorting algorithms maintain the relative order of records with equal keys. In C++11, they are useful in scenarios like sorting a list of employees by name while preserving their original order based on ID.

Can you give me an example of a stable sorting algorithm in C++11?

Sure! The std::stable_sort function in C++11 is a great example. It sorts elements while keeping the order of equivalent elements intact.

What is the difference between stable and unstable sorting?

Stable sorting ensures that equal elements retain their original order, while unstable sorting does not guarantee this. For instance, if two elements have the same value, their order may change in an unstable sort.

When should I use stable sorting?

You should use stable sorting when the order of equal elements is significant, such as when sorting records by multiple fields.
