Understanding Linked Lists: Sequential Access and Efficient Manipulation

📚 A linked list is a data structure made up of nodes that store data and have references to the next node.

➕ Nodes can be added at the end or at the start of a linked list, and the references are adjusted accordingly.

🔗 Nodes in a linked list can be located at any memory address and are not required to be adjacent to each other.

📜 A linked list consists of nodes, with a head node at the start and a tail node at the end.

🔍 To find elements in a linked list, start from the head and follow the next pointers until reaching the tail.

🔀 The tail node points to null, indicating that it is the last element in the list.

🔗 A linked list does not allow for random access to elements, unlike an array.

🔍 To find a specific element in a linked list, you have to follow the links sequentially.

🔀 Maintaining references to the head and tail of a linked list allows for efficient addition of elements.

📚 Adding a new element to a linked list involves creating a new node and updating the links between nodes.

⏰ Inserting elements in a linked list takes constant time, regardless of the number of nodes in the list.

🗑️ Removing an element from a linked list is efficient and involves updating the links between the adjacent nodes.

🔗 Linked lists can be used to represent sequences of data.

➡️ In a singly linked list, each node has a link to the next node.

↔️ In a doubly linked list, each node has a link to both the next and previous nodes.

🔗 A linked list is a data structure that consists of nodes connected through pointers.

⏮️ Nodes in a linked list can be traversed forward or backward, allowing easy navigation through the data.

🔄 Clicking on hyperlinks in a linked list breaks the previous link, affecting the navigation history.

📚 Linked lists are data structures used for storing and manipulating data.

⏪ Linked lists are commonly used for implementing undo and redo functionalities.

📝 Arrays can be used as an alternative to linked lists for storing multiple items of data.
