曾任微軟中國公司總裁唐駿說：“真可惜，我在很多場合都出過這三題，但到目前為
止，還沒有一個(gè)人能完全答對，有人答對了一題，所以他當(dāng)上了我的助理。


數(shù)學(xué)篇

1、1000!有幾位數(shù)，為什么

2、f(n)=1 n>8 n<12
f(n)=2 n<2
f(n)=3 n=6
f(n)=4 n=other
使用+ - * /和sign(n)函數(shù)組合出f(n)函數(shù)
sign(n)=0 n=0
sign(n)=-1 n<0
sign(n)=1 n>0

3、編一個(gè)程序求質(zhì)數(shù)的和例如f(7)=1+3+5+7+11+13+17=58
