python language   Write the lines of code that will print out all of the data in a Linked List.

Write a program in Java to manipulate a Singly Linked List: Count the number of nodes Insert a new node before the value 5 of Singly Linked List Search an existing element in a Singly linked list (the element of search is given by the user) Suppose List contained the following Test Data: Input data for node 1: 2Input data for node 2 : 3Input data for node 3 : 5 Input data for node 4: 8

Q. What are the advantages of a linked list over an array?   Note: Do it fast

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.

Use python code, carefully read the instructions.

Which is true?   a. A LinkedList offers faster element insertion than an ArrayList   b. A List implements the LinkedList interface   c. A LinkedList implements the ArrayList interface   d. A LinkedList offers faster positional access than an ArrayList

Create an object-oriented program that uses a custom list object to automatically generate and work with a series of random integers. Console Random Integer List How many random integers should the list contain?: 12 Random Integers ======== ======= Integers: 17, 34, 34, 15, 71, 44, 97, 48, 19, 12, 83, 42 Count: 12 Total: 516 Average: 43.0 Continue? (y/n): y Random Integers =============== Integers: 52, 88, 10, 77, 56, 91, 17, 51, 22, 14, 48, 37 Count: 12 Total: 563 Average: 46.917 Continue? (y/n): n Bye! Specifications Create a Random IntList class that inherits the list class. This class should allow a programmer to create a list of random integers from 1 100 by writing a single line of code. For example, a programmer should be able to create a custom list that stores 12 random integers with this line of code: ● ● int_list = RandomIntList (12) To do that, you can use the self keyword to access the list superclass like this: self.append (rand_int) The RandomIntList class should contain…

In Python Write code that creates a LIST (data type) of only the first names of the students who are juniors. call it juniorRoster= Given the folowing data set: studentDataScores =…
