題目描述 給定一個鏈表,兩兩交換其中相鄰的節點,並返回交換后的鏈表。 示例: 說明: 你的算法只能使用常數的額外空間。 你不能只是單純的改變節點內部的值,而是需要實際的進行節點交換。 解題思路 利用遞歸的思想,依次交換 ...
Write a program to find the node at which the intersection of two singly linked lists begins. For example, the following two linked lists ...
We are given a linked list with head as the first node. Let's number the nodes in the list: node_1, node_2, node_3, ... etc. Each node may have ...
Given a non-empty, singly linked list with head node `head`, return a middle node of linked list. If there are two middle nodes, return the second ...
Given the head of a linked list, we repeatedly delete consecutive sequences of nodes that sum to 0 until there are no such sequences. After doing ...
題目描述: 給一個鏈表,兩兩交換其中的節點,然后返回交換后的鏈表。 您在真實的面試中是否遇到過這個題? Yes 樣例 給出 1->2->3->4, 你應該返回的鏈表 ...
對於單鏈表而言,假設交換A、B兩個節點,那么需要交換A與B的next指針以及A、B直接前驅的next指針。 需要注意特殊情況:1、當A與B相鄰時:A->next = B;或者B->next = A; 2、當A和B元素相同時,則沒有必要交換 ...
