Помогите решить задачку по программированию, пожалуйста. (с++)

 #include  

 

template

{ 

	int summ = 0; 

	for (int i = 0; i < size - 1; i++) for (int j = i + 1; j < size; j++) summ += arr[i][j]; 

	int count = (size * size - size) / 2; 

	return std::pair{ summ,count }; 

} 

 

int main() 

{ 

	int H[4][4] =  

	{
