How do I reserve capacity and shrink-to-fit with std::multiset?

When working with `std::multiset` in C++, it is important to understand that `std::multiset` manages its memory dynamically and does not provide direct methods for reserving capacity or performing a shrink-to-fit operation like some other containers (e.g., `std::vector`). However, if you are looking to optimize your use of a `std::multiset`, you can consider utilizing its properties and carefully managing insertions and deletions to improve performance.

Here is a basic example demonstrating the use of `std::multiset` to store duplicate values:

#include <iostream> #include <set> int main() { std::multiset ms; // Insert elements into the multiset ms.insert(5); ms.insert(1); ms.insert(3); ms.insert(5); // Duplicate element // Display elements in the multiset for (const auto& element : ms) { std::cout << element << " "; } std::cout << std::endl; return 0; }
