May 22, 2024 · Introduction to Singly linked list : A singly linked list is a set of nodes where each node has two fields 'data' and 'link'. The 'data' field stores actual piece of information and 'link' field is used to point to next node. Basically the 'link' field stores the address of the next node.

Inserting an item at the head of the list requires 3 steps. 1. Create a new node. Insert the item in the datafield of the node. 2. Set the new node’s next pointer to the node current headis pointing to. 3. Make the headpointer point to the newly added node. Fig 2: Insertion at the head of the list
To insert an item at the end of the list, use following steps. 1. Seek through the list until the final node is reached. 2. Create a new node using the item to be inserted. 3. Set the last node’s nextpointer to the newly created node. 4. Set the next pointer of the new node to null. Fig 3: Insertion at the end of the list (Steps 1 and 2 are merged ...
To insert an item anywhere between the first and the last node, use the following steps. 1. Seek through the list until the desired node N (after which you want to insert the new node) is found. 2. Create a new node using the item to be inserted. 3. Set the new node’s nextpointer to the node N. 4. Set N’s nextpointer to the newly created node. Fig ...
Searching for an item in the list requires the following step. 1. Start with the head. 2. If the data matches, your search is complete. 3. If the data does not match, go to the next node and repeat step 2. 4. If the nextof the item is null, we reach the end of the list and data is not found in the list.
For all the delete operations, please keep in mind that, the object needs to be deleted from the heap memory. Languages like Java, Python have Garbage Collector that takes care of this but in C/C++ you need to delete the objects yourself Use the following steps to delete the item at the headof the linked list. 1. Set the nextpointer of the first no...
Use the following steps to delete the item at the end of the list. 1. Seek through the list until you get to the last node (You might need to keep track of the previous node as well). 2. Set the previous node’s nextto null. 3. Delete the last node. Fig 6: Deletion at the end of the list
Search the list until you find the item you are looking for (You might need to keep track of the previous node as well). Let’s call this node N.Set N’s previous node’s next to the N’s next node’s next.Delete N.Learn what is singly linked list, how it differs from array, and how to perform various operations on it. See examples, diagrams, and C code for insertion, deletion, traversing, and searching in singly linked list.
May 22, 2024 · A linked list is a fundamental data structure in computer science. It consists of nodes where each node contains data and a reference (link) to the next node in the sequence. This allows for dynamic memory allocation and efficient insertion and deletion operations compared to arrays. Linked List Data Structure.

Learn what a linked list is, how it works, and how to implement it in different programming languages. A linked list is a linear data structure that consists of nodes connected by pointers.
Learn how to declare, create, add and traverse a singly linked list in C language. A singly linked list is a collection of nodes where each node points to the next node in the chain.
