我对C编程语言还比较陌生,并且一直在玩耍以熟悉它,但是我不确定如何使用下面要尝试的结构和数据来实际实现链表。 )。基本上,目标是从带有头和尾的单链列表中添加一个项目。
更新:我试图在我的add函数中编写一些代码,但还没有对它进行排序,但这是什么样子?
代码源
<%=form_for(:search_results, url:{controller: :search_results, action: :index}, html:{id:"quickSearch"}) do | f| %>
...form fields...
<% end %>
答案 0 :(得分:-1)
首先,正确定义您的结构。
SELECT person, COUNT(*)
FROM (
SELECT * FROM table
ALL LEFT JOIN table
USING variant
)
GROUP BY person
HAVING COUNT(*) == 1;
现在,您尝试使用插入作为插入排序技术。
typedef struct car{
char car_model[32],car_name[32];
};
typedef struct myList{
myList * next;
car * carObject;
};
现在,您需要两个功能
void insertElementByTitle(MyList* someList, CarObjects* someCar){
\\I assume someList is pointing the head of the linked list
\\One more assumption that, the Linked List is already sorted and need to inset
\\someCar in the correct position.
MyList *secondPointer = someList->next;
while(secondPointer != null)
{
if(ifCarIsInBetweenSomeListAndSecondPointer(someList,secondPointer,someCar))
{
someList->next = newNode(someCar);
someList->next->next=secondPointer;
break;
}
someList = secondPointer; secondPointer = secondPointer->next;
}
if(secondPointer == null)
{
someList->next = newNode(someCar);
}
}
