题目标签:Linked List 题目让我们自己设计一个 linked list,可以是单向和双向的.这里选的是单向,题目并不是很难,但要考虑到所有的情况,具体看code. Java Solution: Runtime:  56 ms, faster than 21.21% Memory Usage: 45.2 MB, less than 88.89% 完成日期:07/08/2019 关键点:edge cases public class ListNode { int val; ListNode…

这道题是LeetCode里的第707到题.这是在学习链表时碰见的. 题目要求: 设计链表的实现.您可以选择使用单链表或双链表.单链表中的节点应该具有两个属性:val 和 next.val 是当前节点的值,next 是指向下一个节点的指针/引用.如果要使用双向链表,则还需要一个属性 prev 以指示链表中的上一个节点.假设链表中的所有节点都是 0-index 的. 在链表类中实现这些功能: get(index):获取链表中第 index 个节点的值.如果索引无效,则返回-1. addAtHead(…
