Update. . .
I have finally completed the Day-02 puzzle. I started on these puzzles a week later, so I am behind, not to mention, slow.
Because I am a thorough type person, for me, the tricky parts were in determining what items were: Increasing, Decreasing, Inc/Dec, or the Same (c for 'center'), and capturing the value amounts for the Inc/Dec etc., and then reporting those as detail in the final report.
I just need to clean up the output view and make a few changes to the UI and Report view. Hopefully, I will show the results later today.
