problem_description: Statement
  
  We have three boxes A, B, and C, each of which contains an integer.  
  Currently, the boxes A, B, and C contain the integers X, Y, and Z,
  respectively.  
  We will now do the operations below in order. Find the content of each box
  afterward.
  
    * Swap the contents of the boxes A and B
    * Swap the contents of the boxes A and C
