Linked lists use dynamic memory allocation i.e. they grow and shrink accordingly. It is collection of nodes.Node has two parts, which are data and link. These are explained below.Operations on linked listsThere are three types of operations on linked lists which are as follows −InsertionDeletionTraversingDeletionIdentify the node.Adjust the links in ...
