Example 3, 4 of variadic templates

	}
	begin++;

	return maxValue ;
}

template<typename Iterator>
Iterator getMaxData(Iterator begin, Iterator end) {
	return _getMaxData(begin, end, getMaxCmpObj());
}

template<typename _TP>
inline _TP Max(initializer_list<_TP> _l) {
	return  *getMaxData(_l.begin(), _l.end());
}

int maximum(int n) {
	return n;
}

template<typename... types>
int maximum(int n, types... arg) {
