bool push( elementtype x, deque d );
elementtype pop( deque d );
bool inject( elementtype x, deque d );
elementtype eject( deque d );
其中deque
結構定義如下:
typedef int position;
typedef struct qnode *ptrtoqnode;
struct qnode ;
typedef ptrtoqnode deque;
注意:push
和inject
應該在正常執行完操作後返回true,或者在出現非正常情況時返回false。當front
和rear
相等時隊列為空,pop
和eject
必須返回由裁判程式定義的error
。
#include #include #define error -1
typedef int elementtype;
typedef enum operation;
typedef enum bool;
typedef int position;
typedef struct qnode *ptrtoqnode;
struct qnode ;
typedef ptrtoqnode deque;
deque createdeque( int maxsize )
bool push( elementtype x, deque d );
elementtype pop( deque d );
bool inject( elementtype x, deque d );
elementtype eject( deque d );
operation getop(); /* 裁判實現,細節不表 */
void printdeque( deque d ); /* 裁判實現,細節不表 */
int main()
}return 0;
}/* 你的**將被嵌在這裡 */
