20 Questions
What should the code look like to insert a new node at the beginning of the linked list?
c++ void insertFirst(int key, int data) { struct node *link = (struct node*) malloc(sizeof(struct node)); link->key = key; link->data = data; link->next = head; head = link; }
What is the purpose of the 'sort' function in the given code snippet?
It arranges the nodes in ascending order based on their 'data' values.
What is the purpose of the 'printList' function in the given code snippet?
It displays the data and key values of each node in the linked list.
What does the operation of inserting a new node between two existing nodes involve?
Pointing the next node at the left to the new node and then pointing the new node at C.
What is an important characteristic of a polynomial as described in the given text?
Each term consists of real number coefficients with a non-negative integer degree.
What is the main advantage of a doubly linked list over a singly linked list?
A DLL can be traversed in both forward and backward direction
What is the purpose of maintaining a previous pointer in a doubly linked list?
To enable traversal in both forward and backward direction
In a circular linked list, what makes it useful for implementing a queue?
No need to maintain front and rear pointers
What additional operation can be quickly performed on a doubly linked list compared to a singly linked list?
Insertion before a given node
Why is it advantageous for a circular linked list to support traversal from any node?
To enable applications to repeatedly go around the list
What is the purpose of the 'prev' pointer in a doubly linked list?
To maintain a reference to the previous node in the list
What is the main advantage of a doubly linked list over a singly linked list?
Ease of insertion and deletion at any position
In a doubly linked list, what operation involves adding a node after a given node?
Insert
What additional pointer does a doubly linked list have compared to a singly linked list?
Previous pointer
How does the insertion of a new node at the front of a doubly linked list affect the existing nodes?
The new node becomes the new head of the list
What is a significant advantage of a Doubly Linked List (DLL) over a Singly Linked List (SLL)?
A DLL can be implemented with a single pointer
In a Circular Linked List, what makes it useful for implementing a queue?
Node can be added only at the end of the list
What is the purpose of maintaining a previous pointer in a Doubly Linked List?
To quickly delete a node at the end of the list
What additional space requirement does every node of a Doubly Linked List have compared to a Singly Linked List?
Extra space for an additional data field
Why is it advantageous for Circular Linked Lists to allow traversal from any node?
It enables faster deletion of nodes at the end of the list
