1. Linked List CycleTopic linksTitle Requirements:Given A linked list, determine if it has a cycle in it.Follow up:Can you solve it without using extra space?Just see this problem, it is easy to write down the following procedure:1 BOOLHascycle (ListNode *head) {2ListNode *a = head, *b =head;3 while(a)4 {5b =

1. Single-Link list code: includes the tail interpolation method, insert, delete operation.A single linked list with a head node is also easy to insert and delete in the first position, and does not require additional discussion.#include #include typedef struct LINKLIST{int key;Linklist *next;}linklist;linklist* Create_end (){Linklist *head= (linklist *) malloc (

Determine if the two linked lists intersect, to find the intersection (assuming that the linked list does not have a ring)Determine if the two linked lists intersect to find the intersection (assuming that the linked list may have

Idea: The difficulty of this algorithm is difficult to have a reference to a random node in the list, you can not determine which node the reference points to, but we can use the choice of reference to solve the problem. Using the original linked list as a reference, head is a node of the original list, and the next of

double-ended linked list: A double-ended list is very similar to a traditional linked list. Just a new attribute is added-that is, the reference to the last link node as shown: Because there is a direct reference to the last link. So the double-ended

1. Static linked list Members of a struct can be of various types of pointer variables, and when a struct has one or more members of the base type that is the type of the struct, the struct is called "reference to its own structure". Such as: struct link { char ch; struct link *p; A P is a pointer member that can point to a struct link type variable. Therefore, A.P = a is a valid expression, a

If the linked list intersects we can also judge, the rest is to get the linked list intersection nodeTopicGive the head pointers of two unidirectional lists, such as H1,H2, to determine if the two lists intersectProblem solving steps Determine if two "ring-free" linked
