How to pass template function to function parameters?

Question

C++ / C#

Hello. There are two template functions max and min, you need to test them) I don’t want to write extra code, I want one testFuncTemplate function that will take three arguments: T a, T b, T (*f)) (T& a, T& b).
But as far as I understand, the compiler cannot determine the type of the passed function, how can this be done?

Answer 1

testFuncTemplate(a, b, func<T>)
testFuncTemplate(a, b, func<decltype(a)>)
