Suppose the backing array, a, of an ArrayStack is in the following state: a: What is the index of element F after the following series of method calls? remove (2) remove ( 3 ) remove (0) remove (1) add (1,A) add (1, B) add(0, C) Suppose the backing array, a, of an ArrayStack is in the following state: a : What is the final state of the backing array after the following series of method calls? remove (2) remove (3) remove (0) remove (1) add (1, A) add (1, B) add (0,C) Enter your answer as a list of elements, each element separated by a comma and space. If a a slot in the array is empty, write EMPTY. For example, if your answer were to be the backing array pictured in the diagram, you would need to enter [A, B,C,D,E,F, EMPTY, EMPTY] The following questions all ask about operations performed on an ArrayQueue with a backing array, a, in the current state: a Question 13 (1 point) Suppose the backing array, a, of an ArrayQueue is in the following state: a: n=3j=2len(a)=4 What is the final state of the backing array after the series of method calls below? add (D) Enter your answer as a list of elements, each element separated by a comma and space. If a a slot in the array is empty, write EMPTY. For example, if your answer were to be the backing array pictured in the diagram, you would need to enter [C, EMPTY, A, B] A. Suppose the backing array, a, of an ArrayQueue is in the following state: a: n=3j=2len(a)=4 What is the value of j after executing the following series of method calls? add (D) add (E) A. Question 15 (1 point) Suppose the backing array, a, of an ArrayQueue is in the following state: a: n=3j=2len(a)=4 What is the value of j after executing the following series of method calls? add (D) add (E) remove () A. Question 16 (1 point) Suppose the backing array, a, of an ArrayQueue is in the following state: a : After the series of method calls below, what is the index of the element E relative to the ArrayQueue that the user is aware of? add(D) add(E) remove () remove () A Question 17 (1 point) Suppose the backing array, a, of an ArrayQueue is in the following state: a: n=3j=2len(a)=4 What is the final state of the backing array after the series of method calls below? add(D) add(E) remove () remove () Enter your answer as a list of elements, each element separated by a comma and space. If a a slot in the array is empty, write EMPTY. For example, if your answer were to be the backing array pictured in the diagram, you would need to enter [C, EMPTY, A, B]
