Which of the following is NOT a characteristic of a static data structure?

Memory size can change during runtime

Memory allocated at compile-time

What does the term "persistent data structure" refer to?

A structure that exists beyond program execution

A structure that is allocated in memory

A structure used in temporary algorithms

A structure that is deleted when the program ends

What are the disadvantages of arrays?

There are chances of wastage of memory space if elements inserted in an array are lesser than the allocated size

Index value of an array can be negative

Elements are sequentially accessed

Data structure like queue or stack cannot be implemented

Which of the following statement(s) about stack data structure is/are NOT correct?

Stack is the FIFO data structure

Top of the Stack always contain the new node

Null link is present in the last node at the bottom of the stack

Linked List are used for implementing Stacks

A queue with insert/delete defined for both front and rear ends of the queue

A queue implemented with both singly and doubly linked lists

A queue with insert/delete defined for front side of the queue

A queue implemented with a doubly linked list

One of the differences between a queue and a stack is:

Queues use two ends of the structure; stacks use only one.

Queues require dynamic memory, but stacks do not.

Stacks require dynamic memory, but queues do not.

Stacks use two ends of the structure, and queues use only one

Which of this best describes an array?

Container of objects of similar types

A data structure that shows a hierarchical behavior

Arrays are immutable once initialized

What are the advantages of arrays?

Easier to store elements of same data type

Objects of mixed data types can be stored

Elements in an array cannot be sorted

Index of first element of an array is 1

What are the disadvantages of arrays?

There are chances of wastage of memory space if elements inserted in an array are lesser than the allocated size

Data structure like queue or stack cannot be implemented

Index value of an array can be negative

Elements are sequentially accessed

How can we describe an array in the best possible way?

Container that stores the elements of similar types

The Array shows a hierarchical structure.

The Array is not a data structure

What is the functionality of the following code?

Inserting a node at the beginning of the list

Deleting a node at the beginning of the list

Inserting a node at the end of the list

Deleting a node at the end of the list

Entries in a stack are "ordered". What is the meaning of this statement?

There is a Sequential entry that is one by one

A collection of stacks is sortable

Stack entries may be compared with the '

The entries are stored in a linked list

Which of these is not an application of a linked list?

For separate chaining in hash-tables

How do you insert an element at the beginning of the list?

public void insertBegin(Node node) { node.setNext(head); head = node; size++; }

public void insertBegin(Node node) { head = node; node.setNext(head); size++; }

public void insertBegin(Node node) { Node temp = head.getNext() node.setNext(temp); head = node; size++; }

public void insertBegin(Node node) { Node temp = head.getNext() node.setNext(temp); node = head; size++; }

What is a Linked List in data structure?

It is a type of data structure that consists of nodes, where each node contains a data field and a reference(link) to the next node in the sequence.

It is a linear data structure where each element is stored at a contiguous location and elements are accessed sequentially from the first element.

It is a non-linear data structure where each data element is connected to several other data elements in a hierarchical manner.

It is a special type of data structure that can be perceived as a complete binary tree.

What is a Doubly Linked List in data structure?

It is a type of linked list where each node contains a data field and two references, one to the next node and one to the previous node.

It is a type of linked list where each node contains a data field and a reference only to the next node.

It is a type of linked list where each node contains a data field and a reference only to the previous node.

It is a type of linked list where each node contains two data fields and a reference to the next node.
