C++ 数据结构模板 队列 栈 动态链表 模板 Queue Stack List

C++数据结构模板,可以实现基本功能,用法和stl差不多,比如Q.pop();Q.push(a);Q.front();...... 

(由于动态链表用的不多,若有错误望各位大神不吝赐教:)

队列:

 1 class Queue
 2 {
 3     private:
 4     int    Head,Tail,Size;
 5     int    val[30010];
 6 
 7     public:
 8     
 9     Queue()
10     {
11         Head=0;
12         Tail=-1;
13         Size=0;
14         memset(val,0,sizeof(val));
15     }
16 
17     inline    bool    empty()
18     {
19         return Size==0;
20     }
21     
22     inline    void    push(const int & ele)
23     {
24         Tail=(Tail+1)%30000;
25         Size++;
26         val[Tail]=ele;
27         return ;
28     }
29     
30     inline    void    pop()
31     {
32         if(Size==0)return ;
33         Head=(Head+1)%30000;
34         Size--;
35         return ;
36     }
37     
38     inline    int    front()
39     {
40         if(Size==0)return 0;
41         return val[Head];
42     }
43     
44     inline    int    back()
45     {
46         if(Size==0)return 0;
47         return val[Tail];
48     }
49     
50     inline    int    size()
51     {
52         return    Size;
53     }
54 
55     inline    void    clear()
56     {
57         Head=0;
58         Tail=-1;
59         Size=0;
60         memset(val,0,sizeof(val));
61         return ;
62     }
63 }Q;

 栈:

class    stack
{
    private:

    int    Size;
    int    val[50100];
    
    int    h_top;
    
    public:
    
    inline    int    top()
    {
        return val[h_top];
    }
    
    inline    int    size()
    {
        return Size;
    }
    
    inline    bool    pop()
    {
        if(Size==0)return false;
        val[h_top]=0;
        h_top--;
        Size--;
        return true;
    }
    
    inline    bool    push(int    temp_s)
    {
        h_top++;
        Size++;
        val[h_top]=temp_s;
        return true;
    }
    
    inline    void    clear()
    {
        memset(val,0,sizeof(val));
        h_top=-1;
        Size=0;
        return ;
    }
    
    inline    bool    empty()
    {
        return Size==0;
    }
}st;
