How do I remove duplicates with std::set?

If you want to remove duplicates from a collection of values in C++, you can utilize the `std::set` container. The `std::set` automatically manages unique values, meaning if you add a duplicate, it simply won't be added again. Here’s a brief example demonstrating how to use `std::set` to eliminate duplicates.

#include <iostream>
#include <set>
#include <vector>

int main() {
    std::vector<int> vec = {1, 2, 3, 2, 4, 1, 5};
    std::set<int> uniqueSet(vec.begin(), vec.end());

    std::cout << "Unique values: " << std::endl;
    for (const auto &value : uniqueSet) {
        std::cout << value << " ";
    }
    std::cout << std::endl;

    return 0;
}
