Topic: Singly Linked ListImplement the following functions in C++ program. Read the question carefully. (See attached photo for reference) void isEmpty() This method will return true if the linked list is empty, otherwise return false. void clear() This method will empty your linked list. Effectively, this should and already has been called in your destructor (i.e., the ~LinkedList() method) so that it will deallocate the nodes created first before deallocating the linked list itself.
With Head node or not? statement is: if(p->rlink == null) output << "The data doesn't exist."; O a. It is a Doubly linked list without Head node. O b. It is a Doubly linked list with Head node.
5. The following function indexCounter aims to find and return all the indices of the element x in a list L. if x is not in the list L, return an empty list. However, the implementation has a flaw, so that many times it will return error message. Can you fix the flaw? def indexCounter(L, x): indexList [] startIndex = 0 while startIndex < len(L): indexList.append (L.index (x, startIndex)) startIndex = L.index (x, startIndex) + 1 return indexList
Think about the following example: A computer program builds and modifies a linked list like follows: Normally, the program would keep tabs on two unique nodes, which are as follows: An explanation of how to use the null reference in the linked list's node in two common circumstances
What do you mean by a list that is linked twice?
What does the following function do for a given Linked List? void fun1(struct node* head){if(head == NULL)return;fun1(head->next);printf("%d ", head->data);}
The program requires me to remove all item for a list, but when doing the test case for it, it only removes one. What would be the problem in this code?Given code: #include "MovieList.h"#include <iostream> using namespace std;// Constructor functionMovieList::MovieList() { top = nullptr; } // Destructor functionMovieList::~MovieList() { MovieNode *p = nullptr; while (top->next != nullptr) { p = top; top = top->next; delete p; } delete top; p = nullptr; top = nullptr; } void MovieList::display(ostream &out) { MovieNode *t = top; int pos = 0; // Function to display the movie list while (t != nullptr) { out << pos << ": " << t->title << endl; pos++; t = t->next; } } int MovieList::count() { MovieNode *t = top; int pos = 0; // Counting based off the movie list while (t != nullptr) { pos++; t = t->next; } return pos; } void…
With Head node or not? statement is: if(first->llink == first) output << "List is empty"; O a. It is a Doubly linked list without Head node. O b. It is a Doubly linked list with Head node.
void listEmployees (void) { for (int i=0; i 10000. Make a guess about why the comparison function takes 2 struct Employee parameters (as opposed to struct Employee *) **
In c++, how do I display the last node in a linked list?
struct insert_at_back_of_sll { // Function takes a constant Book as a parameter, inserts that book at the // back of a singly linked list, and returns nothing. void operator()(const Book& book) { /// TO-DO (3) /// // Write the lines of code to insert "book" at the back of "my_sll". Since // the SLL has no size() function and no tail pointer, you must walk the // list looking for the last node. // // HINT: Do not attempt to insert after "my_sll.end()". // ///// END-T0-DO (3) ||||// } std::forward_list& my_sll; };
Every time you write a non-const member function for a linked list, you should always think about if that function is preserving your class invariants. Group of answer choices A. True B. False
