Program Plan Intro

Reverse the queue of integers in odd-numbered positions

Program plan:

  • Import necessary packages.
  • Create a class “QueueRevOdd”,
    • Define the method “rearrange ()” that accepts queue of integers,
      • Construct “Stack” object.
      • Calculate the size of the queue.
      • Execute till queue size,
        • Check whether the position is even,
          • Insert the element removed from the queue into the same queue.
        • Otherwise,
          • Insert the element removed from the queue into the stack.
      • Execute till queue size,
        • Check whether the position is even,
          • Insert the element removed from the queue into the same queue.
        • Otherwise,
          • Insert the element popped out from the stack into the queue.
      • Print the queue of integers after reversed the order of all the elements in the odd-numbered positions.
    • Define the method “main()”,
      • Create two objects for “LinkedList”.
      • Add integers into the queue.
      • Print the queue of integers.
      • Call the method “reverseHalf()” with queue as parameter.

Draw a system/level-0 diagram for this scenario: You are developing a new customer relationship management system for the BEC store, which rents out movies to customers. Customers will provide comments on new products, and request rental extensions and new products, each of which will be stored into the system and used by the manager for purchasing movies, extra copies, etc. Each month, one employee of BEC will select their favorite movie pick of that week, which will be stored in the system. The actual inventory information will be stored in the Entertainment Tracker system, and would be retrieved by this new system as and when necessary. Example of what a level-0 diagram looks like is attached.
