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...

WebListNode *pre = head; ListNode *cur = head; And the opening brace belongs in column 0 (I guess you don't agree, but there are - or were anyway - tools that rely on this). An alternative implementation might use a function to find the number of entries in the list and another to return a specified entry (size - n - 1, in this case). Web11 apr. 2024 · 题目描述： 给定一个链表，返回链表开始入环的第一个节点。如果链表无环，则返回null。为了表示给定链表中的环，我们使用整数 pos 来表示链表尾连接到链表中的位置（索引从 0 开始）。如果 pos 是 -1，则在该链表中没有环。注意，pos 仅仅是用于标识环的情况，并不会作为参数传递到函数中。
Web7 apr. 2024 · 1、无哨兵位的头结点. 先取两个链表中，第一个节点小的结点作为头结点head，再迭代取数值小的结点先尾插，数值大的结点后尾插，. 对于单链表的尾插，是先找到尾，再插入新的结点，取一个结点找一次尾，时间复杂度为O (N^2)，效率很低，此时需要一 …
