来自主题: Mathematics版 - [help]a probability problem
given Z_i \in {0,1}^n, i = 1,2,...
p(Z_i) \neq 0 for all Z_i
find out the pdf of Y = Z_1\oplus Z_2\oplus ...
\oplus is bitwise XOR operator
and further, calculate the expectation of number of "1"s in Y
is it a uniform distribution or normal distribution?
would the expectation of number of "1"s in Y be n/2?
thx

来自主题: Programming版 - scala 真是一个无法无天的糟货
哈哈,主要还是FP粉喜欢说往脸上贴金说FP接近数学,所以搞了一些奇怪的符号,弄得
人不像人,鬼不像鬼的,普通程序员读了困惑,数学家读了更困惑。但是C, Java等传
统的计算机语言,从一开始定位就是给计算机用的编程语言,从来没有说和数学有任何
关系,所以所有符号都是计算机用符号,包括^位运算符,这个就是实实在在的计算机
符号。而数学上用来表示XOR的符号是oplus(LaTex)这样的符号,所以完全没有任何关
系,只要不要往数学上扯。
