最有效的存储1024 * 1024位的方式 [英] Most efficient way of storing 1024*1024 bits
问题描述
嗨
我需要一种时间和空间有效的方式来存储多达600万位。时间
效率比空间效率更重要因为我要通过钻头进行搜索
。
关于tores
Hi
I need a time and space efficient way of storing up to 6 million bits. Time
efficency is more important then space efficency as I''m going to do searches
through the bit-set.
regards tores

嗯，什么你想做什么样的搜索？对于速度你想要什么，你可以使用内置函数，string.find和那种
的东西。因此，请相应地选择数据格式。
Umm, what kind of searches do you want to do? For speed you want to
use built-in functions wherever you can, string.find and that kind of
thing. So choose your data format accordingly.

六兆字节是在现代计算机上几乎没有任何东西。我会将这些东西存储为0字符串。和1，然后使用.find（或者可能是
in关键字）进行搜索。
这不起作用好吧，如果你要改变字符串，
虽然。

Six megabytes is pretty much nothing on a modern computer. I''d store
the things as a string of "0" and "1", and then use .find (or maybe
the in keyword) for doing the searches.
This doesn''t work very well if you''re going to mutate the string,
though.
