a.

Program Plan Intro

Find output for the given Stack

Program plan:

  • Import necessary packages.
  • Create a class “StackQu”,
    • Define the method “mystery1()” that accepts stack,
      • Create the object for “Queue”.
      • Execute while stack is non-empty,
        • Find the value of top of “Stack”.
        • Add the value into the “Queue”.
        • Again add the same value into the “Queue”.
      • Execute while queue is non-empty,
        • Add the element removed from the queue into the “Stack”.
      • Print stack.
    • Define the method “main()”,
      • Create object for “Stack”.
      • Call the “push()” method of stack to add the elements “2”, “6”, and “1” into the stack one by one.
      • Call the method “mystery1()” with stack as a parameter.
