1 Linked List 和 Python 基础操作 1.1 链表原理 数组之后,链表是第二种基础的数据存储结构。和数组的连续存储不同,链表是的存储方式更加灵活,可以连续也可以不连续。不连续的存储单位通过上一个元素的”next“指针指出,也就是说,单个存储单位不仅存储元素的值,还存储下一个单位的地址信息。
代码: 于是乎,新建一个链表,next用两个链表当前位置去比较,谁的小就放谁。当一个链表放完之后,说明另外一个链表剩下的元素都比较大,再放进去就好。 该题目简单,因为已经是两个排序好的链表了。 以下是Python代码,并有测试过程。 #coding:utf-8#Definition for singly-linked list.classListNode(object):def__...
for each linked list l in lists − if is in not 0, then insert I into a heap res := null and res_next := null Do one infinite loop − temp := min of heap if heap has no element, then return res if res is 0, then res := temp, res_next := temp temp := next elemen...
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.Example:Input: 1->2->4, 1->3->4Output: 1->1->2->3->4->4 题意 将两个有序链表合并为一个新的有序链表并返回。新链表是通过拼接给定的...

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: ...
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,只不过这里的数据是链表,思路就是判断当前节点数值和下一...
