How does the performance of C++ set iterators compare to other containers?

Can you explain how the performance of C++ set iterators compares to other STL containers?

Sure! C++ set iterators are generally slower than vector or deque iterators because sets are implemented as balanced trees, which require more overhead for traversal.

What about the time complexity for operations like insertion and deletion?

For sets, both insertion and deletion operations have a time complexity of O(log n) due to the tree structure, while vectors have O(n) for deletion.

Are there scenarios where using a set iterator is more beneficial?

Yes, if you need to maintain a sorted collection with unique elements and perform frequent searches, sets are very efficient.

How do set iterators handle duplicates?

Set iterators do not allow duplicates, as sets inherently store only unique elements. Attempting to insert a duplicate will simply be ignored.
