What is linked list data structure?

In this tutorial, you will learn about linked list data structure and it's implementation in Python, Java, C, and C++. A linked list is a linear data structure that includes a series of connected nodes. Here, each node stores the data and the address of the next node. For example,

What is the difference between a single linked list and a double linked list?

1. Single-linked list: In a singly linked list, each node contains a reference to the next node in the sequence. Traversing a singly linked list is done in a forward direction. 2. Double-linked list: In a doubly linked list, each node contains references to both the next and previous nodes.

What are the advantages of a linked list?

Insertion and Deletion: Adding or removing elements from a linked list is efficient, especially for large lists. Flexibility: Linked lists can be easily reorganized and modified without requiring a contiguous block of memory. Random Access: Unlike arrays, linked lists do not allow direct access to elements by index.

Why are vectors not linked linked list?

Vectors are not linked linked list, they provide random access and are contiguous just like arrays. In order to achieve this they re-allocate memory under the hood. List is designed to allow quick insertions and deletions, while not invalidating any references or iterators except the ones to the deleted element.
