Given the head of a linked list, find all the values that appear more than once in the list and delete the nodes that have any of those values. ...
Given a linked list, remove the nth node from the end of list and return its head. For example, Note: Given n will always be valid. Try to do ...
题目描述 给定一个链表，删除链表的倒数第 n 个节点，并且返回链表的头结点。 示例： 说明： 给定的 n 保证是有效的。 进阶： 你能尝试使用一趟扫描实现吗？ 解题思路 典型的利用双指针法解题。首先让指针first指向头节点 ...
Write a function to delete a node (except the tail) in a singly linked list, given only access to that node. Supposed the linked list is 1 -> ...
Given a singly linked list, return a random node's value from the linked list. Each node must have the same probability of being chosen. Follow ...
