有12个外表一模一样的小球，其中有一个的质量和其他11个球不一样（11个球的质量完全相同） 而且该球不知道是轻点还是重点。现在给你一个天平（无砝码），只有3次测量机会，请你找出该球。(12 looks exactly the same ball, which has a quality and not the same as the other 11 balls (11 balls in the quality of the identical) and that the ball does not know the point or focus light. Now to give you a balance (no weight), only 3 measurements chance, you find the ball.)
