Only Me and Me

慢慢看就知道了

The rise of civilization

 
Andrei说这是位于bay area的某一Microsoft Competitor的一道面试题,我问是不是Google,他说can neither confirm nor deny…
 
Anyway, here is the problem:
 
说有100个硬币放在桌上,其中10个是反面向上,90个正面向上。现在蒙上你的眼睛,你可以将硬币分成2堆,也可以将硬币翻面,但你不能通过触觉来确定硬币是正面还是反面。问怎么操作从而使2堆有同样数目的硬币反面向上。
 
Should be fairly easy.  Took me 5 minutes (read, that’s considered slow).
 
==========================================================================================
 
 
听不懂歌词的意思,因为似乎是一种原始部落的语言。但其中蕴含的那种温柔而磅礴的气势,又仿佛确实带我穿越浩瀚的历史长流,回到最初的地方去见证人类文明崛起时洒落在地平线上的那末曙光。
 
夜深,轻轻掩上工作室的门,天地之间,变成只有我,这乐声,那些书,和我的兄弟们。

    @ anonymous: 是不能证明什么,就是个玩意儿,没公司特别拿这个当真。就是答不上来的话,你自己的心理状态会被影响。

    @WRD: Yup, separating those into a 10-coin pile and a 90-coin pile and flip everything in the 10-coin pile, : )
