  Linked Lists A linked list is a structure in which objects refer to the same kind of object, and where: the objects, called nodes, are linked in a linear sequence. we keep a reference to the rst node of the list (called the \front" or \head"). The nodes are used to store data. For example, here is a class for nodes in a linked list of ints:

  Linked List Basics A linked-list is a sequence of data structures which are connected together via links. Linked List is a sequence of links which contains items. Each link contains a connection to another link. Linked list the second most used data structure after array. Following are important terms to understand the concepts of Linked List.

  elements in a linked list, which are not natural operations on arrays, since arrays have a fixed size. On the other hand access to an element in the middle of the list is usually O(n), where n is the length of the list. An item in a linked list consists of a struct containing the data element and a pointer to another linked list.

  Linked Lists • Linked Lists consists of Nodes • Nodes are connected by forward pointers • And have pointers to the record contents • Pointers: Addresses of objects in memory • This is how Python finds objects • E.g. if you define a class without __str__ and __repr__ dunder, this is how an instance will be printed • It prints the id of the object

  We can store the data in an array or a linked list and each operation can be implemented by iterating over all the elements of the array or list and possibly adding or removing an element. This kind of implementation is easy, but not very efficient. Does this really matter? Computers are becoming faster and faster. Maybe the ob-

  Recursion and Linked Lists Let us begin with a simple definition of a recursive search in a LL. Suppose we are looking for a node in a list. Then either the search node is the first one on the list or node must be on a smaller list (that is a list that contains all nodes but the first node, we typically call this the tail of the list). We can ...
