32 bit 就是 31 bit 的数字的2倍啊
a=rand31()
b=rand31()
c=a+b
c is rand32()

这里大牛多，我来问一下。跟那个老题rand5生成rand7类似，我这样写对吗。谢谢

I think, here the 31, 32 is the bit number.
If the assumption is that, both of them are uniformly distributed,
I think we can combine two 31bits to one 62bis, and just take 32 of them,
because each bit is uniformly
distributed as well.
