Given a linked list, remove the nth node from the end of list and return its head. For example, Given linked list: 1->2->3->4->5, and n = 2. After removing the second node from the end, the linked list becomes 1->2->3->5. Note: Given n will always be valid. Try to d...
Given a linked list, remove thenthnode from the end of list and return its head. For example, Given linked list:1->2->3->4->5, andn= 2. After removing the second node from the end, the linked list becomes1->2->3->5. Note: Givennwill always be valid. Try to do this in ...
After removing the second node from the end, the linked list becomes 1->2->3->5. Note: Givennwill always be valid. 方法一:双指针 删除倒数第n个点,我们首先得找到倒数第n个点才行。因为链表只能从头开始找,倒数第n个点就是正数第m-n(设链表长是m)。我让第一个指针先走n个点然后和第二个指针...
After removing the second node from the end, the linked list becomes 1->2->3->5. Note: Given n will always be valid. Try to do this in one pass. 移除链表中倒数第n个节点; 写一个函数来确定要删除的是第几个节点,方法是获取链表总长度len,那么我们要删除的就是第 nth = len - n 个节点...
next; checkNode = checkNode.next; } copyNode.next = copyNode.next.next; return head; } } 题目信息 Given the head of a linked list, remove the nth node from the end of the list and return its head. 给定一个链表的头节点,删除链表末尾的第 n 个节点,并返回链表的头节点。 示例 解题...
After removing the second node from the end, the linked list becomes 1->2->3->5. Note: Given n will always be valid. Follow up: Could you do this in one pass? 思路: 这道题让我们移除链表倒数第N个节点,限定n一定是有效的,即n不会大于链表中的元素总数。还有题目要求我们一次遍历解...
