再來看C++,由於STL已內建一些容器,所以不需再重新實作linked list,有兩個選擇:std::vector或者std::list。std::vector的優點是non-sequential access超快,新增資料於後端超快,但insert和erase任意資料則超慢;std::list則剛好相反,insert和erase速度超快,但non-sequential access超慢,由於本例只有新增與non-sequentia...

我在LinkedList.h中用extern声明了这个变量: extern LinkedList* canQueue; 然后在main.c中,我通过将变量发送到LinkedList.c中的函数来初始化该变量,如下所示: LinkedList *canQueue=createList(); 这是LinkedList.c中的create函数: LinkedList* createList() /*creates empty linked list*/ { LinkedList* m 浏览...
2. 链表 (Linked List) 链表是由一组节点组成的线性集合,每个节点都包含数据元素和一个指向下一个节点的指针。与数组相比,链表中的元素在内存中可能是非连续的。 适用场景:链表是在需要频繁插入或删除元素时的理想选择,因为这些操作只需要改变一些指针,而不需要移动整个数组。例如,如果你正在实现一个历史记录功能,...
