Q1: Write a method to insert an array of elements at index in a single linked list and then display this list. The method receives this array by parameters. 12:54 AM Q2: Write a method to multiply the odd numbers and add the even numbers for a single linked list data structure, then display the results. The method receives this list by parameters. 12:54 AMI Q3: Write a complete project and test it to execute the single-linked list data structure with all functions including the methods in questions 1& 2. 12:54 AM all in java

Given the following program segment. Assume the node is in the usual info-link form with the info of the type int. (list and ptr are reference variable of the LinkedListNode type. What is the output of this program? list = new LinkedListNode (); list.info = 20; ptr = new LinkedListNode (); ptr.info = 28; ptr.link= null; list.link ptr; ptr = list; list = new LinkedListNode (); list.info = 55; list.link = ptr; ptr = new LinkedListNode (); ptr.info = 30; ptr.link= list; list = ptr; ptr = new LinkedListNode (); ptr.info = 42; ptr.link= list.link; list.link= ptr; ptr = list; while (ptr!= null) { } System.out.println (ptr.info); ptr = ptr.link;

Create the Singly Linked List after having executed the following methods. Each item must have a headand tailreference. Whenever a method is not expected or invalid, write Exception. Only the process not the code •addHead("Dancing") •addHead("Backup") •addHead("Backup") •addTail("Backup") •addTail("Backup") •removeHead()

for some reason in the list object when i try to insert the code into a linked list it inserts the characters backwards instead of forwards. I have to input characters from a user created string individually into a linked list. the linked list cannot change because the teacher requires me to use the specified code in my textbook. i would appreciate if you would explain the problem and solution in words and not code. the code is in Java is there a way to get this program to output correctly?
