- In Java Write a method rearrange that takes a queue of integers as a parameter and rearranges the order of the values so that all of the even values appear before the odd values and that otherwise preserves the original order of the list. For example, suppose a queue called q stores this sequence of values: front [3, 5, 4, 17, 6, 83, 1, 84, 16, 37] back Then the call of rearrange(q); should rearrange the queue to store the following sequence of values: front [4, 6, 84, 16, 3, 5, 17, 83, 1, 37] back Notice that all of the evens appear at the front of the queue followed by the odds and that the order of the evens is the same as in the original list and the order of the odds is the same as in the original list. You may use one stack as temporary storage.If an array of size 6 is used to implement a circular queue, and the current values of rear and front are O and 3 respectively, when one element is removed from the queue and two more elements are added, what are the values of rear and front, respectively? O 1, 5 O 4, 2 5, 1 O 2, 3 None of the aboveWrite a method called removeDuplicates that accepts a PriorityQueue of integers as a parameter and modifies the queue's state so that any element that is equal to another element in the queue is removed. For example, if the queue stores [7, 7, 8, 8, 8, 10, 45, 45], your method should modify the queue to store [7, 8, 10, 45]. You may use one stack or queue as auxiliary storage.
- Create a priority queue of integer values with duplicates. No more than 20 values. Remove Duplicates Write a method called removeDuplicates that accepts a PriorityQueue of integers as a parameter and modifies the queue's state so that any element that is equal to another element in the queue is removed. For example, if the queue stores [7, 7, 8, 8, 8, 10, 45, 45], your method should modify the queue to store [7, 8, 10, 45]. You may use one stack or queue as temporary storage. kthSmallest Write a method called kthSmallest that accepts a PriorityQueue of integers and an integer k as parameters and returns the kth-smallest integer from the priority queue (where k=1 would represent the very smallest). For example, if the queue passed stores the integers [42, 50, 45, 78, 61] and k is 4, return the fourth-smallest integer, which is 61. If k is 0 or negative or greater than the size of the queue, return -1 and print "Invalid Argument." You may use one stack or queue as temporary storage.…please use Java languege Write a method “removeEvensQueue” that takes a queue (type: interface Queue) of integers. This method should remove all the even values from it and keep all the rest (odd numbers) in the queue in the same order they were before.Write a class MyArrayQueue that Inherit the ArrayBoundedQueue class show in screen shot and such that all the following methods are implemented in java: public String toString();// Creates and returns a string that correctly represents the current queue. public void remove(int count);// Removes the front count elements from the queue.// Throw QueueUnderflowException with message of "Less than count elements in queue." //if there are less than count elements in the queue. public void reQueue();// Dequeue an element from front, and enqueue the element back to rear of the queue.// Throw QueueUnderflowException with message of "No element in queue."// if there is no element in the queue. public void clear();// Clear entire queue.public void reverse();// Reverse queue content. Hint: you may use LinkedStack ADT.} public int space(); //return how many open spaces does the queue have still available.
- Write a method named reorder that accepts as a parameter a queue of integers that are already sorted by absolute value, and modifies it so that the integers are sorted normally. For example, if a named q stores the following elements: queue variable front {1, -2, 4, 5, -7, -9, -12, 28, -34} back Then the call of reorder (q); should modify it to store the following values: front {-34, -12, -9, -7, -2, 1, 4, 5, 28) back Constraints: You may use a single stack as auxiliary storage. Java solution code goes here Method: Write a Java method as described, not a complete program or class.The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts public class ItemNode { private String item; private ItemNode nextNodeRef; // Reference to the next node public ItemNode() { item = ""; nextNodeRef = null; } // Constructor public ItemNode(String itemInit) { this.item = itemInit; this.nextNodeRef = null; } // Constructor public ItemNode(String itemInit, ItemNode nextLoc) {…
- implement this method: numOccurrencesRec(LNode node, int n, int key) – This method takes as parameters a reference to the head of a linked list, a position specified by n, and a key. It returns the number of occurrences of the key in the linked list beginning at the n-th node. If n = 0, it means you should search in the entire linked list. If n = 1, then you should skip the first node in the list.An array of size MAX_SIZE is used to implement a queue. head, tail, and size are tracked. Suppose front is 0 and rear is MAX_SIZE -1. How many elements are present in the queue? a. 0 b. MAX_SIZE-1 c. MAX_SIZE d. 1QUESTION 9 Write a complete Java program to implement a QUEUE in a bank using LinkedList class as follows: • Provide the menu as shown below; use an infinite loop; stop when user opts 4. 1. Add a customer 2. Remove a customer 3. Show the queue 4. Exit • Add a customer should add an int number at the end of queue using the method addLast(). • Remove a customer should delete the int from front using the method removeFirst(). Show the queue should display the numbers in queue using the method System.out.printIn(). For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
