单链表(Singly Linked List): 单链表中每个节点只有一个指针,即指向下一个节点的指针。 双链表(Doubly Linked List): 双链表中每个节点有两个指针,一个指向下一个节点,另一个指向前一个节点,使得可以双向遍历链表。 头节点(Head): 链表的头节点是链表的第一个节点,用于标识整个链表的起始位置。 尾节点(Tail)...
Define another class to create a Doubly Linked List with two nodes i.e head and tail. Initially, these values will be null. Create a function for adding nodes in the linked list, It will first check whether the head is null and then insert the node as the head. ...

Acircular linked listis like a singly or doubly linked list with the first node, the "head", and the last node, the "tail", connected. In singly or doubly linked lists, we can find the start and end of a list by just checking if the links arenull. But for circular linked lists,...
of the sequence table is stored using an array, and then a get, set, and add method must bebased on the array, and the linked list isbased on the pointer. When we consider the data relationship in the object, we must consider the properties of the pointer. Pointer's point and value...
Have a pointer to a single head node, which serves as the first node in the list Have a pointer to a single tail node, which serves as the last node in the list Require the pointers at the head of the list to be updated after addition to or removal of the head ...

Given a (singly) linked list with head noderoot, write a function to split the linked list intokconsecutive linked list "parts". The length of each part should be as equal as possible: no two parts should have a size differing by more than 1. This may lead to some parts being null....
A 'head' pointer which is used for pointing to the start of the record in a list. A 'tail' pointer which is used for pointing to the last node. The key factor in the last node is that its subsequent pointer points to nothing (NULL). ...
