next = even_head # 把奇数的最后一个节点,和首个偶数节点连接起来 return head # 时间复杂度 O(n) # 空间负载都 O(1) 链表为空情况处理: 如果链表为空,即 head 为None,直接返回 None 初始化指针: odd 初始化为链表的头节点,即第一个奇数节点。 even 初始化为链表的第二个节点,即第一个偶数节点。
https://leetcode.com/problems/odd-even-linked-list/ 建两个dummy node,一个维护奇数节点构成的链表,另一个维护偶数节点构成的链表,最后再拼接起来。注意偶数节点构成的链表最后一个节点的next域要置空,否则可能会导致出现环路。 classSolution{public:ListNode*oddEvenList(ListNode* head){if(!head || !head-...
起因是8、9行,因为odd和even本身已经是head和head->next两个节点,再设置next为NULL就相当于截断了原链表,even->next=NULL,进不了while循环。如果把18、19注释掉,不会RE。 1classSolution {2public:3ListNode* oddEvenList(ListNode*head) {4if(head == NULL)returnhead;5if(head->next == NULL)returnhead...

LeetCode 328:奇偶链表 Odd Even Linked List 简介:给定一个单链表,把所有的奇数节点和偶数节点分别排在一起。请注意,这里的奇数节点和偶数节点指的是节点编号的奇偶性,而不是节点的值的奇偶性。请尝试使用原地算法完成。你的算法的空间复杂度应为 O(1),时间复杂度应为 O(nodes),nodes 为节点总数。
