题目 Remove all elements from a linked list of integers that have value val. Example Given: 1 –> 2 –> 6 –> 3 –> 4 –> 5 –> 6, val = 6 Return: 1 –> 2 –> 3 –> 4 –> 5 Credits: Special thanks to @mithmatt for adding this problem and…

删除链表中等于给定值 val 的所有节点. Remove all elements from a linked list of integers that have value val. 示例: 输入: 1->2->6->3->4->5->6, val = 6 输出: 1->2->3->4->5 解题思路: 两种方法,一种是迭代法,从第一个节点开始,遇到值相同的节点就将其删除.链表的删除操作是直接将删除节点的前一个节点指向删除节点的后一个节点即可…

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…

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…

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 ==…

Remove all elements from a linked list of integers that have value val. Example Given: 1 --> 2 --> 6 --> 3 --> 4 --> 5 --> 6, val = 6 Return: 1 --> 2 --> 3 --> 4 --> 5 解题思路: JAVA实现如下: public ListNode removeElements(ListNode h…
