well, that solution is correct for the numbers you gave. if you give more, then the number of solutions narrows. that is a viable answer. give more numbers if you want less answers
There are 100 coins scattered in a dark room. 90 have heads facing up and 10 have tails up. You cannot distinguish (by feel, etc.) which coins are which. How do you sort the coins into two piles that contain the same number of tails?
