In computer science, a linked list is a fundamental data structure consisting of nodes with data and a reference to the next node. The nodes are liked with each other by pointers. This allows for dynamic memory allocation and efficient insertion and deletion operations as compared to arrays.
A linked list is a data structure where the nodes are connected by a pointer, the pointer will point to the next node and it’s data element. Each node consists of data element and pointer. All nodes in a linked list are connected with each other by pointers (address element).
The link list consists of -> DATA ELEMENT -> POINTER (address), the pointer will contain the address of the next node to which the previous node is pointing.
TYPES of the Linked list are :
Single Linked List
Double Linked list
Circular linked list
NOTE: Both the Single and double linked lists are Linear, But the Circular linked list is circular.
A linked list is a fundamental data structure that consists of nodes with data and a reference to the next node. This allows for dynamic memory allocation and sequential access of data elements. Insertion and deletion operations are efficient and faster compared to arrays.
NOTE: In a linked list, the data element access is sequential in nature, but in the case of an array, the data element access is random. This data structure contrasts with arrays, as the elements are not stored in contiguous memory locations.
Single linked list: Consists of DATA ELEMENT and NEXT POINTER. The data nodes are connected linearly.
Double Linked list: Consists of DATA ELEMENT, PREVIOUS POINTER, and NEXT POINTER. The data nodes are connected linearly.
Circular linked list: Consists of DATA ELEMENT, PREVIOUS POINTER, and NEXT POINTER, The data nodes are connected circularly.
A linked list is a type of data structure in which elements, called nodes, are arranged in a linear and circular order. Each node contains a data element and a reference or link to the next node in the sequence.Linked lists enable efficient insertion and removal of elements at any position by adjusting the pointers between nodes.This flexibility comes at the cost of requiring additional memory to store the pointers, and the need to traverse the list from the beginning to find a specific element.
