void del_dublicate(ElemL1* head)
{
	ElemL1* current = head;
	ElemL1* current2;
	ElemL1* current2prev;
	current2prev = current;
	while (current != NULL)
	{
		current2 = current->next;
		while (current2 != NULL)
		{
			if (issame(current, current2))
			{	
				current2prev->next = current2->next;
				
			}
			else { current2prev = current2; }
			current2 = current2->next;
		}
		current = current->next;
		
	}
	cout << "\nПовторяющиеся элементы удалены\n";
