Remove every node which has a node with a greater value anywhere to the right side of it. Return the head of the modified linked list. Example 1: Input: head = [5,2,13,3,8] Output: [13,8] Explanation: The nodes
【LeetCode】26.Linked List —Remove Nth Node From End of List 从列表末尾删除第n个节点 Given a linked list, remove then-th node from the end of list and return its head. Example: Given linked list:1->2->3->4->5, andn= 2. After removing the second node from the end, the linked...

The given linked list will contain between1and1000nodes. Each node in the linked list has-1000 <= node.val <= 1000. 这道题让从一个链表中移除所有和为0的连续的结点,并给了好几个例子帮助我们理解题意。好久没玩链表的题了,对于一道 Medium 的题来说,应该不会太复杂。其实链表的问题都可以当成数...

structmy_nodenode; 链表节点在插入链表之前也需要进行初始化,使用INIT_LIST_HEAD宏,例如: INIT_LIST_HEAD(&node.list);node.data =42; 2.3 — 添加节点到链表中 链表节点初始化完成后,就可以往链表中添加节点: inlinevoidlist_add(structlist_head *new,structlist_head *head);inlinevoidlist...
node.val = node.next.val; node.next = node.next.next; } } Remove Linked List Elements 伪造表头 复杂度 时间O(N) 空间 O(1) 思路 删除链表所有的特定元素的难点在于如何处理链表头,如果给加一个dummy表头,然后再从dummy表头开始遍历,最后返回dummy表头的next,就没有这么问题了。
