The following method is intended to pop an item from the top of an Integer stack that is implemented as a linked list. However, there is a problem with it. Explain the problem and write the code for the correct implementation. public Integer pop () { if (top != null) { top = top.next; return top.value; return null;

1- A new static method with one parameter which is a head node for a linked list of integers, the method should create a new linked list which is equivalent to the original list of integers but with all repetitions removed, the method's return value is a head reference for the new list. this is what I have but it's not removing repetitions. public static IntLinkedBag removeRepetition (IntLinkedBag b1) { IntNode next; IntNode head = null; LinkedList<Integer> s = new LinkedList<>(); IntNode new_list = new IntNode(0, null); IntNode now = head; IntNode prev = new_list; while (now!= null) { int x = now.data; if (s.contains(x)) { new_list = new_list.next; } else { s.add(x); new_list.next = new IntNode(x, now); new_list = new_list.next; } now = now.next; } return b1; } }…
Use an array and two index variables. Write functions or methods push, pop, and sizeof. Then write a main function or method that will allocate the stack at n=10 and push some strings in ii, print out the size, and then pop some strings from it. Note make stack be be able to hold string variable type. java

Use stacks from the STL to implement a video game library functionality. In this implementation, consider a VideoGame class with title, release year, genre and publisher as variables. Provide setters and getters to these variables. In main, create a stack of video games. Add 5 different game objects into the stack. Then in a loop, for each item that you retrieve from the stack display the game information as follows: TITLEYEARGENREPUBLISHER

in C++ Write a method ‘void addBack(double x)’ that adds value x to the back of a linked list. Assume you have access to a ‘head’ pointer pointing to the first node in the list. Please note that you do NOT have a tail pointer. Be sure to check for any special cases.
Write a method that takes as parameters two sorted stacks of integers s1 and s2 (where the lowest value is at the top) and returns a sorted stack (lowest on top) that contains the values of both s1 and s2. You are allowed to use only the stack operations such as pop, push, and top. You are allowed to use only stacks as temporary storage. No other data structures such as arrays are allowed. The header of the method is: public static Stack mergeSortedStacks (Stack s1, Stack s2) Write a main method in which you create two sorted stacks and call the above method to test it.
