    Provide a comparator that reverses the comparison.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    multiset uses std::less<T> as the default comparison predicate. To reverse the predicate, you'll need std::greater<T>

    Code:
    #include <functional>
    
    std::multiset<int, std::greater<int> > my_multiset;
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.
