Delete from a Linked ListYou can delete either from the beginning, end or from a particular position.1. Delete from beginningPoint head to the second node head = head->next;2. Delete from endTraverse to second last element Change its next pointer to null...
There are three main types of linked lists – singly linked list, doubly linked list, and circular linked lists. A singly linked list consists of a chain of nodes, where each node has a data element and a pointer to the memory location of the next node. This is best demonstrated by ...
