LINKED LIST PYTHON SERIES

Point its next pointer to the struct node containing 2 as the data value.

Create a new struct node and allocate memory to it.

if you wanted to put an element 4 between 1 and 2, the steps would be: The power of a linked list comes from the ability to break the chain and rejoin it.

In just a few steps, we have created a simple linked list with three nodes. If you didn't understand any of the lines above, all you need is a refresher on pointers and structs. Let us create a simple Linked List with three items to understand how this works. Understanding the structure of a linked list node is the key to having a grasp on it.Įach struct node has a data item and a pointer to another struct node. We wrap both the data item and the next node reference in a struct as: struct node Let's see how each node of the linked list is represented. Note: You might have played the game Treasure Hunt, where each clue includes the information about the next clue. To learn about other types, visit Types of Linked List. In this article, we will focus on the singly linked list.

Linked lists can be of multiple types: singly, doubly, and circular linked list. Also, the last node in the linked list can be identified because its next portion points to NULL. You have to start somewhere, so we give the address of the first node a special name called HEAD. Here, each node stores the data and the address of the next node.
