世界上只有2%的人能出答案的迷题的推导过程和答案（有七种答案）



　　前面有人给出了这道出自1981年柏林的德国逻辑思考学院据说就连大名鼎鼎的爱因斯坦也成为此题大伤脑筋的迷题的七种答案和java实现过程。

　　我这里用C++实现过程,我觉得代码写得还可以，如果有兴趣可与我交流。

-the world, only 2% of the people could answer out of the crowds that the derivation process and answers (some answers to seven) was given earlier this Road from the 1981 Berlin Germany logical thinking Institute said even the famous Einstein has become such a headache that large crowds that the seven answers and java implementation process. I use a C implementation process, I think the code can be written, if any interest in sharing with me.
