- An array may contain multiple duplicate values, as shown below. In order to design an algorithm with the best average performance to remove all duplicate values, which of the following data structures should be used? [34, 45, 60, 45, 30, 24, 34, 60] Question 47 options: List Priority queue Hash table StackO(N) is the order of growth execution time of the enqueue operation when using the ArrayBoundedQueue class, assuming a queue size of N. T or FIf N represents the number of elements in the queue, then the enqueue method of the ArrayBoundedQueue class is O(N). true or false
- In Javascript an array can be treated like a queue---a FIFO (first-in, first-out) data structure. Which two array operations that we studied in class can be used together to treat an array as a queue? a. isEmpty() and isFull() b. queue() and unqueue() c. unshift() and pop() d. push() and pop() e. unshift() and shift()Question 9: Draw internal representation of the queue q for each step of the following code: ArrayBoundedQueue<Integer> q = new ArrayBoundedQueue<Integer>(6); q.enqueue(37); q.enqueue(86); q.enqueue(54); q.enqueue(71); q.dequeue(); q.enqueue(97); q.dequeue();A group of students writes their names and unique student ID numbers on sheets of paper.

- Which of the following structures would be the most efficient to use if you wanted to establish a priority queue for quick retrieval? Choose one: a. a doubly linked list that is sorted O b. array of ordered elements a. unordered singly linked list b. unordered singly linked list c. unordered singly linked O d. an unsorted arrayProgramming Radix Sort You will implement Radix Sort on arrays of base 10 integers between 0 and 2,147,483,647(Integer.MAX_VALUE). You will implement RadixSort in a new way using an array of Queuesto sort the values by digit. Your algorithm must run in at most O(n) time. I have given you asimple implementation of a Queue (Queue.java) that inserts and removes elements inconstant time. This is method signature Class to use Programming Radix Sort: package sorting; import java.util.Arrays; public class RadixSorter{ //returns the max value in the array //used to provide the k to counting sort private static int getMax(int[] arr) { int max = Integer.MIN_VALUE; for(int i: arr) { if(i>max) max = i; } return max; } public static void radixSort(int[] arr) { //Get the maximum to know how many digits I have int max = getMax(arr); } } And this is queue Class: package sorting; import…In this problem you are simulating a HOT DOG stand.
