Come across this problem once again in the book The Modern C++ Challenge (problem 18). Wonder how simple and elegant the implementation could be using C++17. Following is my solution. Ideas? ^_^

#include <algorithm>

template <typename Less, typename T, typename... Ts>
constexpr const T& min(Less less, const T& a, const T& b, const Ts&... rems) 
 if constexpr (sizeof...(rems)) 
 return min(less, std::min(a, b, less), rems...);
 
 else 
 return std::min(a, b, less);
