• Dynamic Data Structure. Linked list is a dynamic data structure so it can grow and shrink at runtime by allocating and deallocating memeory.
• Insertion and Deletion. Insertion and deletion of nodes are really easier.
• No Memory Wastage.
• Implementation.
• Memory Usage.
• Traversal.
• Reverse Traversing.
• Accordingly, why ArrayList is faster than linked list?

ArrayList is faster than LinkedList if I randomly access its elements. ArrayList has direct references to every element in the list, so it can get the n-th element in constant time. LinkedList has to traverse the list from the beginning to get to the n-th element. LinkedList is faster than ArrayList for deletion.

What is a link list in data structure?

In computer science, a linked list is a linear collection of data elements, whose order is not given by their physical placement in memory. Instead, each element points to the next. It is a data structure consisting of a collection of nodes which together represent a sequence.

ArrayList is implemented as a resizable array. It’s elements can be accessed directly by using the get and set methods, since ArrayList is essentially an array. LinkedList is implemented as a double linked list. Its performance on add and remove is better than Arraylist, but worse on get and set methods.

## What is a single linked list?

Singly Linked Lists are a type of data structure. In a singly linked list, each node in the list stores the contents and a pointer or reference to the next node in the list. It does not store any pointer or reference to the previous node. The last node in a single linked list points to nothing.

## What is the data structure?

A data structure is a specialized format for organizing and storing data. General data structure types include the array, the file, the record, the table, the tree, and so on. Any data structure is designed to organize data to suit a specific purpose so that it can be accessed and worked with in appropriate ways.

## What is a node in data structure?

A node is a basic unit used in computer science. Nodes are devices or data points on a larger network. Devices such as a personal computer, cell phone, or printer are nodes. When defining nodes on the internet, a node is anything that has an IP address.

## What is the binary search?

In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array.

## What is the merge sort?

Merge sort is a sorting technique based on divide and conquer technique. With worst-case time complexity being Ο(n log n), it is one of the most respected algorithms. Merge sort first divides the array into equal halves and then combines them in a sorted manner.

## What is a tree data structure?

In computer science, a tree is a widely used abstract data type (ADT)—or data structure implementing this ADT—that simulates a hierarchical tree structure, with a root value and subtrees of children with a parent node, represented as a set of linked nodes.

## What do you mean by abstract data type?

In computer science, an abstract data type (ADT) is a mathematical model for data types, where a data type is defined by its behavior (semantics) from the point of view of a user of the data, specifically in terms of possible values, possible operations on data of this type, and the behavior of these operations.

## What do you mean by sorting in data structure?

Data Structure – Sorting Techniques. Advertisements. Sorting refers to arranging data in a particular format. Sorting algorithm specifies the way to arrange data in a particular order. Most common orders are in numerical or lexicographical order.

## What is the priority queue?

In computer science, a priority queue is an abstract data type which is like a regular queue or stack data structure, but where additionally each element has a “priority” associated with it. In a priority queue, an element with high priority is served before an element with low priority.

## What do you mean by stack in data structure?

Stacks A stack is a basic data structure that can be logically thought of as a linear structure represented by a real physical stack or pile, a structure where insertion and deletion of items takes place at one end called top of the stack. This structure is used all throughout programming.

## What is a link list in data structure?

In computer science, a linked list is a linear collection of data elements, whose order is not given by their physical placement in memory. Instead, each element points to the next. It is a data structure consisting of a collection of nodes which together represent a sequence.

## What is a doubly linked list?

In computer science, a doubly linked list is a linked data structure that consists of a set of sequentially linked records called nodes. Each node contains two fields, called links, that are references to the previous and to the next node in the sequence of nodes.

• 1) A DLL can be traversed in both forward and backward direction.
• 2) The delete operation in DLL is more efficient if pointer to the node to be deleted is given.
• ## Is linked list a linear or non linear data structure?

Non-linear tends to imply a structure beyond a simple sequential pattern. A linked list can be considered linear if each node is pointing at another node in contrast to trees and other data structures where there may be multiple pointers within a node. A binary tree for example, is much harder to imagine as a line.

## What is the structure of an array?

Array data structure. An array is stored such that the position of each element can be computed from its index tuple by a mathematical formula. The simplest type of data structure is a linear array, also called one-dimensional array.

## What is a graph in data structures?

In computer science, a graph is an abstract data type that is meant to implement the undirected graph and directed graph concepts from mathematics, specifically the field of graph theory. The vertices may be part of the graph structure, or may be external entities represented by integer indices or references.

## What is meant by recursion in data structure?

Advertisements. Some computer programming languages allow a module or function to call itself. This technique is known as recursion. In recursion, a function α either calls itself directly or calls a function β that in turn calls the original function α. The function α is called recursive function.

## What is a complete binary tree?

A full binary tree (sometimes proper binary tree or 2-tree) is a tree in which every node other than the leaves has two children. A complete binary tree is a binary tree in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible.
