(前面 LeetCode 23 也已经介绍过相关的知识:王几行xing:【LeetCode-转码刷题】LeetCode 21「合并链表」) 这里数组(array)、链表(linked list)、栈(stack)和队列(queue)的概念及其在Python中的实现方式相互交错,故我们也先回顾一下。 栈的Python 中的实现方式: list 列表; collections.dqueue,双向队列(对应的是...

19. Remove Nth Node From End of List & collections 依然特雷希 通信测试攻城狮 来自专栏 · Python Leetcode本题是 Leetcode Top 100 liked questions 中的第十题。19. Remove Nth Node From End of ListMediumGiven a linked list, remove the n-th node from the end of list and return its head....
82. Remove Duplicates from Sorted List II Given a sorted linked list, delete all nodes that have duplicate numbers, leaving onlydistinctnumbers from the original list. Example 1: Input:1->2->3->3->4->4->5Output:1->2->5 Example 2: ...
83. Remove Duplicates from Sorted List Given a sorted linked list, delete all duplicates such that each element appear onlyonce. Example 1: Input:1->1->2Output:1->2 Example 2: Input:1->1->2->3->3Output:1->2->3 思路: 这一题和26题移除数组中重复的元素一样都是去重,只不过这里的数...
