Without any further ado, here is a list of Leetcode problems you can solve to get better at linked list:闲话少说,这里列出了您可以解决的 Leetcode 问题,以便更好地使用链表: Reverse Linked List 反向链表Description: Given the head of a singly linked list, reverse the list and return its new...
The singly-linked list is the easiest of the linked list, which has one link per node. Pointer To create linked list in C/C++ we must have a clear understanding about pointer. Now I will explain in brief what is pointer and how it works. A pointer is a variable that contains the add...
If two lists have intersection, then their last nodes must be the same one. So when pA/pB reaches the end of a list, record the last element of A/B respectively. If the two last elements are not the same one, then the two lists have no intersections. /** * Definition for singly-...
Implement an algorithm to delete a node in the middle of a singly linked list, given only access to that node. Example Given1->2->3->4, and node3. return1->2->4 删除的方法就是用后面的值覆盖前面的值,注意避免OBOB /*** Definition for ListNode. * public class ListNode { * int val...
Design your implementation of the linked list. You can choose to use a singly or doubly linked list.

Write a program to find the node at which the intersection of two singly linked lists begins. For example, the following two linked lists: begin to intersect at node c1.Example 1: Input: intersectVal = 8, listA = [4,1,8,4,5], listB = [5,0,1,8,4,5], skipA = 2, skipB ...
题目保证链表中节点的值互不相同 若使用 C 或 C++ 语言,你不需要 free 或 delete 被删除的节点 /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) : val(x), next(NULL) {} * }; */ class Solution { public: ListNode* deleteNo...
