Pretty ugly solution, relies on knowledge about the data. Works.

This is a disgusting solution, but it works. The speed challenge wants you to take up to 393 steps (on average), this takes 81

If you know anyone that wrote code like this for a real problem, don't hire them.

	// Why does this work:
	int addrInfoRet = getaddrinfo(host.c_str(), port.c_str(), &hints, &remoteHost);
	auto deleter = [](addrinfo* p){ if (p) {freeaddrinfo (p);} };

	std::unique_ptr<addrinfo, decltype(deleter)> remoteHostContainer(remoteHost, deleter);
	
	// But this doesn't:
	int addrInfoRet = getaddrinfo(host.c_str(), port.c_str(), &hints, &remoteHost);

	std::unique_ptr<addrinfo, decltype(freeaddrinfo)> remoteHostContainer(remoteHost, freeaddrinfo);
