Program Plan Intro

Rearrange queue of integers

Program plan:

  • Import necessary packages.
  • Create a class “QueueArrange”,
    • Define the method “rearrange ()” that accepts queue of integers,
      • Construct “Stack” object.
      • Calculate the size of the queue.
      • Execute till queue size,
        • Assign the element removed from the queue.
        • Check whether the element is even,
          • Insert the element into the queue.
        • Otherwise,
          • Insert the element into the stack.
      • Calculate the stack size
      • Execute till stack becomes empty,
        • Insert the element removed from the stack to queue.
      • Execute till the stack size,
        • Insert the element removed from the queue into the same queue.
      • Execute till queue size minus stack size,
        • Insert the element removed from the queue into the stack.
      • Execute till stack becomes empty,
        • Insert the element popped out from the stack to queue.
      • Print the queue of integers after rearranged.
    • Define the method “main()”,
      • Create two objects for “LinkedList”.
      • Add integers into the queue.
      • Print the queue of integers.
      • Call the method “rearrange()” with queue as parameter.

Create a static function in C# where poachers appear and attempt to hunt animals. It gets the location of the closest animal to itself. Take account of that the animal also move too, so it should update the closest location (x, y) everytime it moves to a new location. Use winforms to show the movements of poachers.
