Sort a linked list using insertion sort. 含义：用插入排序来对列表进行排序 思路：可以构建一个临时的链表，然后将待排序的链表的每一个节点插入到临时链表中 // 插入排序 public ListNode insertionSortList(ListNode he 阅读全文
摘要：
Given a singly linked list L: L0→L1→…→Ln-1→Ln,reorder it to: L0→Ln→L1→Ln-1→L2→Ln-2→… You must do this in-place without altering the nodes' values. For 阅读全文

Given a sorted linked list, delete all nodes that have duplicate numbers, leaving only distinct numbers from the original list. For example,Given 1->2 阅读全文
摘要：
Given a linked list, swap every two adjacent nodes and return its head. For example,Given 1->2->3->4, you should return the list as 2->1->4->3. Your a 阅读全文

摘要：
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 -> 2 -> 3 - 阅读全文
