What are some alternatives to std::multiset in C++?

What are some alternatives to std::multiset in C++?

You can consider using std::set, std::vector with sorting, or std::unordered_multiset depending on your needs.

What are the performance differences between these alternatives?

std::set offers O(log n) for insertions and lookups, while std::unordered_multiset provides average O(1) for these operations.

When should I use std::vector instead?

Use std::vector when you need fast random access and can manage sorting manually, especially for small datasets.

Are there any specific use cases for std::unordered_multiset?

Yes, std::unordered_multiset is great for scenarios where you need fast insertions and lookups without order.
