Are they equivalent? 1) ArrayList list = new ArrayList(); 2) ArrayList list = new ArrayList<>();

PROBLEM STATEMENT: In this problem you will need to return the first elementfrom the ArrayList. import java.util.ArrayList;public class RetrieveSpecifiedElement{public static int solution(ArrayList<Integer> list){// ↓↓↓↓ your code goes here ↓↓↓↓return 0; Can you help me with this question The language is Java

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…

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

C++ Hello im trying to make a list for my code but i cant use the <list> library, how would i make a list for my linked list array based hashtable code wordlist: incase you want to test the entire code a aaa hello goodbye   #pragma once //hashtable.h #include <iostream> #include <string> #include <list> #include <cstdlib> #include "word.h" using namespace std;   class HashTable { int BUCKET; list<Word>* table; public: HashTable(int W);   //to check if the table is empty bool isEmpty() const;   //to insert a key into the hashtable void insertItem(string& x);   //to delete a key from the hashtable void deleteItem(int key);   int hashFunction(Word x);   //to look for the key in the table bool searchTable(string& key); void displayHash();   }; //hashtable.cpp #include "hashtable.h" #include <iostream> HashTable::HashTable(int W) { table = new list < Word >[W]; BUCKET = W; return; }   //to check if the table is empty bool…

What benefits does a linked list have over an array?
