Who is the Culprit Robot?Logic Level 1
You have 100 robots at home to make your jobs done. And they can't lie.
Today you see one of your show-piece broken, one of your robots did it and all of them except you know who's that.
So you ask each of them "You did it?", they can only answer "Yes" or "No".
What is the maximum number of robots you have to ask before you're sure who the culprit is?
