n中可能的子集数量呈指数：你认为需要多少内存？b / b $

因为这显然是家庭作业（请在发布之前查看这个小组的常见问题解答，

）我会留给你确切知道公式是什么。


它可能也在您的教科书中说明。

是的，但是/会/有人为你做家庭作业吗？


希望不是。

它不是功课，你笨蛋。如果你无法帮助别人，那么只需保持闭嘴，因为它只会显示你是多么愚蠢。

I have an array of n integers and I want a function that returns a list of
arrays of all possible subsets. Can someone provide me with the code?

Thanks.

The number of possible subsets is exponential in n: how much memory do
you think that will require?

Since this is obviously HOMEWORK (see this group''s FAQ before posting,
please) I''ll leave it to you to figure out exactly what the formula is.

It''s probably also stated in your textbook.

Can someone provide me with the code?

Yes, but /will/ someone do your HOMEWORK for you?

Hopefully not.

See the FAQ''s item about posting HOMEWORK questions.

--
A: Because it messes up the order in which people normally read text.
Q: Why is it such a bad thing?
A: Top-posting.
Q: What is the most annoying thing on usenet and in e-mail?

Its not homework, you dumbass. If you cannot help someone then simply keep
your mouth shut because it only goes to show how stupid you are.
