I thought it was an interesting challenge, and well suited to RPN calculators. Even though I was disappointed in what I came up with in the end, the process of looking for ways to shave off a line here or there, or save a register by using stackrobatics, reminded me of the days when this whole hobby started, programming the HP-25. Good times. Thank you!
