I solved only one problem today, but it's a big one!

     Yes, it's the "zebra puzzle", a famous logic puzzle attributed to Albert Einstein! It's really a big one, which took me a afternoon's time and 5 pages of paper to write down my solution. What's more, just now I find the ink of my pen is almost used up!
