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。
1 <= Node.val <= 10 ^ 5 样例 思路:快慢指针/双指针 本题是 LeetCode 876 - 链表的中间结点 和LeetCode 203 - 移除链表元素 的加强版,数据范围加大,并需要删除中间结点。 对于链表的题目,一般都可以使用一个哨兵结点。 本题使用哨兵结点,方便处理删除头结点这种边界情况。 因为本题需要删除中间结点,所以...
