203题是在链表中删除一个固定的值,83题是在链表中删除重复的数值,但要保留一个:82也是删除重复的数值,但重复的都删除,不保留. 比如[1.2.2.3],83题要求的结果是[1.2.3],82题要求的结果是[1,3]. 这种题用递归去做比较方便思考,特别是这种重复的数值.递归就是只遍历当前的节点的情况,之前的不用管,之后的以当前节点为出发点思考问题. 203. Remove Linked List Elements class Solution { public: ListNode* remo…
Question 203. Remove Linked List Elements Solution 题目大意:从链表中删除给定的数 思路:遍历链表,如果该节点的值等于给的数就删除该节点,注意首节点 Java实现: public ListNode removeElements(ListNode head, int val) { ListNode cur = head; while (cur != null) { if (cur.next != null && cur.next.val ==…
203. Remove Linked List Elements[easy] Remove all elements from a linked list of integers that have value val. ExampleGiven: 1 --> 2 --> 6 --> 3 --> 4 --> 5 --> 6, val = 6Return: 1 --> 2 --> 3 --> 4 --> 5 Credits:Special than…
Remove all elements from a linked list of integers that have value val. Example: Input: ->->->->->->, val = Output: ->->->-> 本题的思路很简单,就是单纯的删除链表元素操作,如果头结点的元素就是给定的val值,需要借助虚结点dummy去判断. 方法一:(C++) C++中注意结点的释放 ListNode* removeElem…
Remove Linked List Elements Remove all elements from a linked list of integers that have value val. ExampleGiven: 1 --> 2 --> 6 --> 3 --> 4 --> 5 --> 6, val = 6Return: 1 --> 2 --> 3 --> 4 --> 5 Credits:Special thanks to @mith…
Remove Linked List Elements Remove all elements from a linked list of integers that have value *val*. Example: Input: 1->2->6->3->4->5->6, val = 6 Output: 1->2->3->4->5 解 /** * Definition for singly-linked list. * struct List…
Remove all elements from a linked list of integers that have value val. ExampleGiven: 1 --> 2 --> 6 --> 3 --> 4 --> 5 --> 6, val = 6Return: 1 --> 2 --> 3 --> 4 --> 5 题目标签:Linked List 题目给了我们一个 链表 和一个 val,让我们把链表中 等于 val 的点都去除.…
