日期 2023-06-12 10:48:40(LeetCode 21)Merge Two Sorted Lists
Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. 题目要求: 合并两个有序链表 注意: 不能开辟新的结点空间 解题思路: 1、归并排序,创建一个新的头结点,从头到尾
日期 2023-06-12 10:48:40(LeetCode 82)Remove Duplicates from Sorted List II

日期 2023-06-12 10:48:40[LeetCode] Insertion Sort List
解题思路 对于得到结点current的插入位置,从头结点开始遍历,直到遍历到值大于等于节点current的结点,然后将从该结点到current的前驱结点的所有结点的值依次和current结点的值交换,从而达到将该节点插入所遍历到的位置的目的。 /**************** 解题思路 对于得到结点current的插入位置,从头结点开始遍历,直到遍历到值大于等于节点current的结

题目来源。待字闺中。原创@陈利人 。欢迎大家继续关注微信公众账号“待字闺中” 分析:思路和数据的高速排序一样,都须要找到一个pivot元素、或者节点。然后将数组或者单向链表划分为两个部分。然后递归分别快排。 针对数组进行快排的时候,交换交换不同位置的数值。在分而治之完毕之后,数据就是排序好的。那么单向链表是什么样的情况呢?除了交换节点值之外。是否有其它更好的方法呢?能够改动指针,不进行数值
