and we need to insert 2 into the list. The new node should be inserted between node 1 and node 3. After the insertion, the list should look like this, and we should still return node 3.
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...
这时候,我们可以考虑使用链表(Linked-list) 来替代它,除了对数据的随机访问,链表几乎可以在任何可以使用一维数组的情况中。如果你正巧在使用C或者Java等高级语言,你会发现链表的表现要优于数组很多。 链表其实有许多的种类:单向链表、双向链表、单向循环链表和双向循环链表,接下来,我们基于对象来实现一个单向链表,因为...
LinkedList实现所有可选的列表操作,并允许所有的元素包括null。除了实现 List 接口外,LinkedList 类还为在列表的开头及结尾 get、remove 和 insert 元素提供了统一的命名方法。这些操作允许将链接列表用作堆栈、队列或双端队列。此类实现 Deque 接口,为 add、poll 提供先进先出队列操作,以及其他堆栈和双端队列操作。
Hello everyone, I inserted a new node at the beginning of the linked list but i am not able to print it's data. It still says null Please guide me where i am doing wrong. Thank you! //initial head head = null //after inserting node - 30 at the beginnnig [30]-->null | head...

与ArrayList 一样实现了 List 接口,只是 LinkedList 底层结构为链表.在插入和删除时更优于 ArrayList,而随机访问则比 ArrayList 稍逊. 其允许元素包括 null.除了实现 List 接口外,LinkedList 类还为在列表的开头及结尾 get、remove 和 insert 元素提供了统一的命名方法。这些操作允许将链接列表用作堆栈、队列或双端...
