when I try to deal with 2B:the least round way with python3, I got Memory limit, so I decided to use Numpy to reduce the useage of the memory and CPU, but unfortunately I got runtime error this time, what I want to ask is, do codeforces support Numpy and other program library? If not, how could I use these library in codeforces?

No, you cannot use Numpy on Codeforces. Try HackerRank, for example.
Your english needs improving.
Your English needs 'improvement', not his.
"needs improvement" and "needs improving" are both correct, although the latter is less common. That's a bad attempt to be witty and I'm surprised you have so many upvotes.
When saying "Your english needs improving" the word "improving" is used as a gerund, which English allows a lot. The only mistake in innv's comment is not capitalising the first letter of the word "English", which I wouldn't even call a mistake.
P.S. Yea, the post is very old and recently got bumped, but I might as well rant.
Lol. Didn't know that. I meant only pun,no offence. And probably I got upvotes because of the pun only.
Fair enough. I meant no offence either, just got surprised that so many people agreed that "needs improving" is incorrect.
Of course not everyones English is as good as you to know that..,
So everyone's English need improving

You can't, I checked on python3 and pypy..
