- Java (Inserting Elements in a LinkedLists) Write a program that inserts 100 random integers from 1 to 100 in order into a Java LinkedList object. The program should sort the elements, then calculate the sum of the elements and the floating-point average of the elements.In which scenarios would you prefer to use an array over a linked list, and vice versa?API documentation link ------> https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/ArrayList.html PREVIOUS CODE - import java.util.ArrayList;public class BasicArrayList { // main method public static void main(String[] args) { // create an arraylist of type Integer ArrayList<Integer> basic = new ArrayList<Integer>(); // using loop add elements for(int i=0;i<4;i++){ basic.add(i+1); } // using loop set elements for(int i=0;i<basic.size();i++){ basic.set(i,(basic.get(i)*5)); } // using loop print elements for(int i=0;i<basic.size();i++){ System.out.println(basic.get(i)); } }} Q1) a)Consider how to remove elements from the ArrayList. Give two different lines of code that would both remove 5 from the ArrayList. b)What do you think the contents of the ArrayList will look like after the 5 has been removed? (Sketch or list) c)Now update the BasicArrayList program to remove the 5 (index 1) from the ArrayList. Add this step before the last loop that…
- JavaScript Given a singly linked list of integers, determine whether or not it's a palindrome. // Singly-linked lists are already defined with this interface: // function ListNode(x) { // this.value = x; // this.next = null; // } // function isListPalindrome(head) { } Note: in examples below and tests preview linked lists are presented as arrays just for simplicity of visualization: in real data you will be given a head node l of the linked list Example For l = [0, 1, 0], the output should beisListPalindrome(l) = true; For l = [1, 2, 2, 3], the output should beisListPalindrome(l) = false.Please code in C language. Please use the starter code to help you solve the deleted node and the reverse list. Here is the starter code: #include <stdio.h> #include <ctype.h> #include <stdlib.h> #include <string.h> #include "linkedlist.h" // print an error message by an error number, and return // the function does not exit from the program // the function does not return a value void error_message(enum ErrorNumber errno) { char *messages[] = { "OK", "Memory allocaton failed.", "Deleting a node is not supported.", "The number is not on the list.", "Sorting is not supported.", "Reversing is not supported.", "Token is too long.", "A number should be specified after character d, a, or p.", "Token is not recognized.", "Invalid error number."}; if (errno < 0 || errno > ERR_END) errno = ERR_END; printf("linkedlist: %s\n", messages[errno]); } node *new_node(int v) { node *p =…Question 44 Computer Science A list of elements has a size of 100. Choose the operations where an ArrayList would be faster than a LinkedList.

- What benefits does a linked list have over an array?Question 2: Linked List Implementation You are going to create and implement a new Linked List class. The Java Class name is "StringLinkedList". The Linked List class only stores 'string' data type. You should not change the name of your Java Class. Your program has to implement the following methods for the StringLinked List Class: 1. push(String e) - adds a string to the beginning of the list (discussed in class) 2. printList() prints the linked list starting from the head (discussed in class) 3. deleteAfter(String e) - deletes the string present after the given string input 'e'. 4. updateToLower() - changes the stored string values in the list to lowercase. 5. concatStr(int p1, int p2) - Retrieves the two strings at given node positions p1 and p2. The retrieved strings are joined as a single string. This new string is then pushed to the list using push() method.detemine if the follow statement are true or False and why? screenshots show the ArrayBoundedStack class and StackUnderflowException code If N represents the number of elements on the stack, then the push method of the ArrayBoundedStack class is O(N). While processing this expression ( } ( ) ( ) { { { } [ ] } } ) the highest number of elements on our stack at any one time is 1. If N represents the maximum possible number of elements on the stack, then the ArrayBasedStack constructor is O(N). The following expression is balanced: ( ( ( [ ) ] ) ) Our StackUnderflowException code essentially consists of two simple constructors and "packages" and "extends" statements and nothing else.
- Explain this code by putting comments in detail. Language used is c++. Topic is Linkedlist // void deleteByData(int data) { // if(head->data == data) { // head = head->next; // } // next = head; // Node *prev = next; // while (next != NULL) { // if (next->data == data) { // prev->next = prev->next->next; // } // prev = next; // next = next->next; // } // }; };What is the biggest advantage of linked list over array? Group of answer choices Unlike array, linked list can dynamically grow and shrink With linked list, it is faster to access a specific element than with array Linked list is easier to implement than array Unlike array, linked list can only hold a fixed number of elementsHow to measure the performance of an ArrayList?
