tanithryudoRemember these?
Snagged this from some interview talk. Fun to ponder. Try your wits!
1. You have 3 glasses full of water in a row followed by 3 empty glasses, as so:
[F] [F] [F] [ ] [ ] [ ]
With just moving one (1) glass, how can you make it so that they are lined up alternating full & empty glasses?
2. There is a basket with six eggs inside. Six people each take one. How is it that there is still one (1) egg remaining in the basket?
3. You have two strings that will each burn out completely in one (1) hour. But the burn rate on each string and each part of the string is not uniform (for example, cutting a string in half and burning that half will not be equal to half an hour). Using just the two strings and a lighter, how can you measure out 45 minutes?
4. You have an arbitrary rectangle. Inside it is another arbitrarily sized & located rectangle. How can you draw one line that will bisect both rectangles in area?
Hints (highlight to read):
1. Consider all the combinations of the glasses you can move, and what you can do with them.
2. Consider what else each person could do.
3. Consider all the combinations of where you can start burning the string, and the effects that will have. Start off by figuring out how to measure 30 minutes.
4. Consider geometry and how do you normally bisect any shape into equal areas.
