You have been hired to analyze a hacked database. The data is stored in a linked list,constructed from nodes described as follows:struct node{char *fname;char *Iname;struct node *next;};The list has a sentinel node, which is accessible with the already-initialized variablestruct node *sent;The hacker created a series of records where the first name and the last name are the same. Yourgoal is to determine how many hacked records exist.(a) write a function with the protoypeint hackCount(struct node *);whose purpose is to count the number of nodes where the first name is equal to the last name,and return that value.(b) write a function with the prototypetag(struct node*);that accepts a sentinel node, and inserts a new node at the beginning of the list (immediately afterthe sentinel) with fname and Iname each set to the string "hacked"

A function prototype is simply the declaration of a function that specifies function's name,…

QueueArray.java This file implements QueueInterface.java This file has * attributes of an array holding queue elements. An integer represents front * index, an integer for rear index, and an integer to keep track number of * elements in the queue. An overloaded constructor accepts an integer for * initializing the queue size, e.g. array size. An enqueue method receives an * object and place the object into the queue. The enqueue method will throw * exception with message "Overflow" when the queue is full. A dequeue method * returns and removes an object from front of the queue. The dequeue method * will throw exception with message "Underflow" when the queue is empty. A size * method returns number of elements in the queue. A toString method returns a * String showing size and all elements in the queue.

EXCEPTION: A linked list cannot represent a set. This is a set data structure without values. Sets have no duplicates. Sets are amenable to mathematical set functions like union and intersection.
The data fields for the inner class Node for a single linked list class contains : reference to the data, reference to the next node, and reference to the previous node. A True B False
In java The following is a class definition of a linked list Node:class Node{int info;Node next;}Assume that head references a linked list and stores in order, the int values 5, 7 and 9. Show the instructions needed to delete the Node with 5 so that head would reference the list 7 and 9.
Project 2: Singly-Linked List The purpose of this assignment is to assess your ability to: ▪Implement sequential search algorithms for linked list structures ▪Implement sequential abstract data types using linked data ▪Analyze and compare algorithms for efficiency using Big-O notation For this assignment, you will implement a singly-linked node class. Use your singly-linked node to implement a singly-linked list class that maintains its elements in ascending order. The SinglyLinkedList class is defined by the following data: ▪A node pointer to the front and the tail of the list Implement the following methods in your class: ▪A default constructor list<T> myList ▪A copy constructor list<T> myList(aList) ▪Access to first elementmyList.front() ▪Access to last elementmyList.back() ▪Insert value myList.insert(val) ▪Remove value at frontmyList.pop_front() ▪Remove value at tailmyList.pop_back() ▪Determine if emptymyList.empty() ▪Return # of elementsmyList.size() ▪Reverse order of…
If you need to announce a Linked List Node structure for recording two data member with Name, Save Money, and a link pointer for next node in C language. The logical view is shown as attached figure. The requirement of data member record is following: Name is spelled by Character with maximal length 16; Save_Money is a positive integer number. Please filled the announcement statements for the Node of Linked List. struct Node { } node_Member; Save_Money; *next;
1 Implement a Queue Data Structure specifically to store integer data using a Singly Linked List. 2 The data members should be private. 3 You need to implement the following public functions: 4 1. Constructor: 5 It initialises the data members as required. 6 7 8 2. enqueue(data) : This function should take one argument of type integer. It enqueues the element into the queue and returns nothing. 3. dequeue(): It dequeues/removes the element from the front of the queue and in turn, returns the element being dequeued or removed. In case the queue is empty, it r 4. front (): 10 11 It returns the element being kept at the front of the queue. In case the queue is empty, it returns -1. 12 5. getSize(): 13 It returns the size of the queue at any given instance of time. 14 6. 1sEmpty(): 15 It returns a boolean value indicating whether the queue is empty or not. 16 Operations Performed on the Stack: 17 Query-1 (Denoted by an integer 1): Enqueues an integer data to the queue. 18 19 Query-2…
