True or False

  • Given a stack implemented as an array, and the following functions performed:

 

Push(A), Push (B), Push(C), Pop(), Push(D), Push(E), Pop(), Push(F)

 

  1. The array will be [A][B][D][F] and the “top” of the stack will be at index 3 where [F] is
  2. The next element that will be removed when Pop is called will be A
  3. If we Push(G), [G] will be inserted at index 0

 

  • Given a queue implemented as an array with a maximum capacity of 5 elements and O(1) insert and remove, and the following functions are performed:

 

Insert(7), Insert(6), Insert(5), Insert(4), Remove(), Remove(), Insert(3), Insert(2), Insert(1), Remove()

 

  1. The removeIndex value will be index 4
  2. The array will be [2][1][ ][4][3]
  3. The insertIndex value will be index 2

 

  • Given a priority queue implemented as a standard linked list with only a head pointer, insert performing at O(n) and remove at O(1), and the following functions performed (higher numbers represent higher priorities):

 

Insert(“Rick”, 75), Insert(“Carol”, 80), Insert(“Daryl”, 65), Remove(), Insert(“Negan”, 60), Insert(“Maggie”, 25), Remove(), Insert(“Michonne”, 55)

 

  1. If Insert(“Eugene”, 40) is called, it will be added as the last node in the linked list
  2. The linked list from head to the end at this point is Rick, Negan, Michonne, and then Maggie
  3. Carol was the first element removed from the priority queue
  4. None of the above
