Lab 1

Tasks

• add a new function that removes all the elements in the queue
• add a new function that adds set of items into the queue
  • E.g: queue.addAll([3,7,1,9])
• add a function that pops (dequeues) N elements from the queue. The function should reject the input if there is no enough element to be removed.
  • E.g: queue.dequeueN(2); // pop 2 elements
• add a new function that prints the content of the queue with their indexes. The output can be something like:
  • 1–>34
  • 2–>30
  • 3–>11
  • 4–>-3
