Implement generic class ArrayStack as discussed in the lectures having following methods: constructor, push, pop, peek, isEmpty, copy constructor, reallocate (private method). Also add following methods to this class: size: returns number of elements in the stack. contains: Search an element in the stack. If found returns true, else returns false. clear: Deletes all elements of the stack and make it empty stack.

Q18) Suppose, we are given a class called Car that has the following 3 attributes named model (string), year (int) and price (float). The function named find_car() takes three input parameters as follows: an object my_car of Car class, a string my_model, and an int age. This function returns True if my_car's model matches the given model and my_car is not more than age years old. Otherwise it returns False Choose the best option to fill the gap on Line# 2. (my_car.my_model == model) and (2022 - my_car.age) <= year (my_car.my_model == model) or (2022 - my_car.age) <= year (my_car.model == my_model) and (2022 - my_car.year) <= age (my_model == model) and (2022 - age) <= year (my_car.model == my_model) or (2022 - my_car.year) <= age
If the following is a circular array based queue of size 99 43 54 76 93 77 18 If rear is at index 1 and front is at index 6, what is the size of the queue? Answer:
*The Question In the Picture Criteria a. Create a class called Queue with member variable queueArr, integer queue array, integer rear, integer front b. i. Initialize rear and front to -1ii. Receive an integer and check if queue is full, if not then insert the integer to the queue arrayiii. Delete front element from queue if front is not equal to rear (empty)iv. Print out the queue array if rear is not equal to front. c. i. Provides a choice to the user if they want to insert, delete or display the queue. ii. According to the user response, the appropriate function is called.
In following code of priority queue using array, I want a method that displays the array, make front and rear counters and a main method to check above two methods: Code: // insert an item at the rear of the queuevoid enqueue(int item) {// Check if the queue is fullif (n == MAX_SIZE - 1) {printf("%s\n", "ERROR: Queue is full");return;}queue[n++] = item;}// removes the item with the maximum priority// search the maximum item in the array and replace it with // the last itemint dequeue() {int item;// Check if the queue is emptyif (n == 0) {printf("%s\n", "ERROR: Queue is empty");return -999999;}int i, max = 0;// find the maximum priorityfor (i = 1; i < n; i++) {if (queue[max] < queue[i]) {max = i;}}item = queue[max];// replace the max with the last elementqueue[max] = queue[n - 1];n = n - 1;return item;}
The following procedure removes the first half of the list passed as a parameter: public static void foo( List myList) { int theSize = myList.size( ) / 2; for( int i = 0; i < theSize; i++ ) myList.remove( 0 ); } What is the running time of foo if myList is a LinkedList? e(1) O e(n Ig n) O(n) O e(n³) e(n?)
14. If a queue is implemented under an ArrayList, how much time does a queue remove an item ? а. О(1) b. O(n) c. 0(n2) d. 0(log n)
What is the purpose of the following method? Assume that both q1 and q2 are not empty and contains the same number of elements. public class QueueEx { public static void method1(ArrayQueue q1, ArrayQueue q2) { Iterator iter1 = q1.iterator(); while (iter1.hasNext()) { int a = iter1.next(); int b = q2.poll(); if (a > b) q2.offer(a); else q2.offer(b): } } Corresponding elements of q1 and q2 are compared, q1 will contain the greater and q2 will contain the smaller among the corresponding elements of q1 and q2. Corresponding elements of q1 and q2 are compared. q1 will contain the smaller and q2 will contain the greater among B the corresponding elements of q1 and q2. Corresponding elements of q1 and q2 are compared. q1 will remain unchanged and q2 will contain the elements which are greater among the corresponding elements of q1 and q2. D All elements of q1 which are greater than the first element of q1 will be added to q2.
We can declare a new array and copy the items of the old queue to new and by this, it will extend the size of the queue.
Assume you have a method (shown below) inside the single linked list class, what does this method do? private E remove () { Node temp = head; if (head != nulI) { head = head.next; size--; return temp.data } else return null; } (A Remove the first node in the list and return the data of the deleted node or null if the list is empty. Remove the node after the node referenced by temp and return the data of the deleted node or null if the list is (в empty. Remove all the nodes of the linked list and return the data of the last node deleted or null if the list is empty.
