Haiku
No, this is not the operating system. Sorry to disappoint. This is actually an interesting question i came across a few days back. The problem is actually quite simple: code generate as many Haikus as the user wants. Now, why this got me interested is because i used to write a couple of Haikus myself. And i was decent at it as well (it was enough to get a couple of them published in my college magazine). So i sat about thinking what the possible methods of generating Japanese 3 line poetry with a 5-7-5 syllable rule via code be possible. Here is one idea that bounced my mind today and i would like to share it.
