What is the performance of std::multiset in C++?

What is the performance of std::multiset in C++?

The performance of std::multiset in C++ is generally logarithmic for insertions, deletions, and lookups, due to its underlying balanced tree structure.

How does it compare to std::set?

Both std::multiset and std::set have similar performance characteristics, but std::multiset allows duplicate elements, while std::set does not.

Are there any scenarios where std::multiset is preferred?

Yes, std::multiset is preferred when you need to maintain a collection of elements with duplicates and still require sorted order.

What are the memory implications of using std::multiset?

std::multiset typically uses more memory than std::vector or std::list due to the overhead of maintaining the tree structure.
