Use a basic array of type int (do not use ArrayList or anything like that).

 

Your Queue should have the following public methods:

  • public void enqueue(int n)
    • O(c) or O(n) when growing the array
  • public int dequeue()
    • O(n)
  • public int peek()
    • O(c)
  • public int size()
    • O(c)
  • public boolean isEmpty()
    • O(c)
