i need it ASAP please
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; } }…
Java Program: please choose an aswer:
Given the interface of the Linked-List struct Node{ int data; Node* next = nullptr; }; class LinkedList{ private: Node* head; Node* tail; public: display_at(int pos) const; ... }; Write a definition for a method display_at. The method takes as a parameter integer that indicates the node's position which data you need to display. Example: list: 5 -> 8 -> 3 -> 10 display_at(1); // will display 5 display_at(4); // will display 10 void LinkedList::display_at(int pos) const{ // your code will go here }
Java programming In the Java programming language, write a method that lists all the elements of the list in reverseorder!
5- Write an efficient java method that computes and returns the height from node t in a btree of any degree. . Please write proper comments in your java code. Your java code should not read or print anything. Assume btree node is defined as follow: private class node{ int count, data(); node parent, link[]:} // end class node private int height(node t){
java program : Given the following method within the ArrayQueue class, what does it do ? public int Undefined(E item) {      int i = front, count = 0;      for ( int j = 0; j < size; j++ )      {                if (! theData[i].equals(item))                  count++;              i = (i + 1) % capacity;      }      return count; } It returns the number of the elements in the queue not equal to the element at the front of the queue and, also item. It returns the number of the elements in the queue not equal to the element at the front of the queue. It returns the number of elements of the queue not equal to item. It returns the number of occurrences of item in the queue.

java program : Given the following method to be considered within the SingleLinkedList class, what does this method do? public void Undefined() {      Node<E> ptr = head;      if (ptr == null || ptr.next == null) return false;      E item1 = ptr.data;      while (ptr.next != null)            ptr = ptr.next;      E item2 = ptr.data;      if (item1.equals(item2))      {              head = head.next;              size--;      } } If the first element of the list is equal to the second element of the list, then the method deletes the second node. If the first element of the list is equal to the last element of the list, then the method deletes the first node. If the first element of the list is equal to the second element of the list, then the method deletes the first node. If the first element of the list is equal to the last element of the list, then the method deletes the last node.
