Listnode newhead null

Web题目描述输入两个单调递增的链表，输出两个链表合成后的链表，当然我们需要合成后的链表满足单调不减规则。基本思路设置一个头结点newHead，newHead初始化乘两个链表中头结点较小的节点。当第一个链表中的节点值小于等于第二个时， 将newHead指向第一个链表节点； 调整正newHea... Web解题思路二：递归法. 递归删除排序链表中的重复元素的思路是将问题分解为两部分：首先处理头节点及其重复元素，然后递归处理剩余链表。. 这种方法的关键在于利用递归处理子链表，并将结果链接到当前节点。. 详细步骤如下：. 递归的基本情况：如果链表 ...
