There is a black table such that u can't see what is inside it..It contains 4 coins placed in at 4-different directions(north, east, south, west).You have to make all the coins facing towards head. You can do following operations: 1. Flip any one coin. 2. Flip adjacent coins. 3. Flip diagonal coins 4. Flip all coins.
After your every answer table makes a random number of rounds(so u r not sure which coin was flipped previously) Also after every flip u can ask a question whether all points are facing head...(if all coins are facing head u will get 'yes' as an answer else 'no') -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
