Rule of baseball in ruby - Last weekend, I went to see baseball game with my six years old kid. I found that the rule of baseball is quite difficult. For example, treating foul ball as strike if the count of strike is under two. There are lots of conditional procedures. So, I write the rule in ruby. Looks nice,isn't it?
