The rule of thumb for the selection of linked list and array:
(1) It is recommended to use an array when you need to access the elements through the index in constant time and know in advance how m
Given a linked list, return the node where the cycle begins. If There is no cycle, return null .Note:do not modify the linked list.Follow up:Can you solve it without using extra space?Subscribe to see which companies asked this questionSolution: The problem is the title linked list
Problem Description:Enter a binary search tree and now convert the two-fork search tree into a sorted doubly linked list. And in the process of conversion, you cannot create any new nodes, only the point of the node pointer in the tree can be adjusted to implement.Analytical:With binary tree sequence traversal, because the middle sequence traversal binary search tree is characterized by small to large acces
Single-linked list is the classic list operation algorithm, single-linked list of the algorithm idea is to reverse the list arrow (assuming that the next pointer is an arrow), the so-called change chain, the chain process is as fo
Title Description:Given a linked list, this list is required to be flipped.Time O (n), Space O (1)Problem Solving Ideas:Set three pointers, temp, prev,head, and flip from beginning to end.The head represents the current node, Prev represents the previous node, and temp represents the next node.Reference code:/** * Definition of ListNode * * class ListNode {* Pub
Lists are used for both database and data structures. So review the list of C (really forget it).struct: (If a pointer to a struct type is defined in the struct, it is well suited for the establishment of a linked list)egstruct student{ int num; float score; struct Student * next;};A static list requires th
Given a linked list, determine if it has a cycle in it.

Note: The linked list loop is not the same as the tail pointer and header pointer, but may form a loop in the middle section. Therefore, you cannot only determine whether the element and the first element overl

Given a non-negative number represented as a singly linked list of digits, plus one to the number.The digits is stored such, the most significant digit was at the head of the list.Example:Input:1->2->3output:1->2->4This problem gives us a linked list, used to simulate a three-digit number, the table head is high, now l
There is a one-way cyclic linked list, reporting data from the beginning, reporting elements that are multiples of M or M. A one-way cyclic linked list is formed based on the order of departure.
Function prototype: void reorder (node ** head, int m );
I personally think that this question is a variant of Joseph's ring.

"The title requires a direct rollover of the list, not a new space."One of the key points of this problem is that when m=1, there is no other node (Leetcode test case without head node) in front of the linked list that needs to be flipped, which brings a little difficulty to solving the problem. A more intuitive and convenient idea is to insert a head node in a
