After searching on the internet I couldn't get a definitive answer, so I am asking here.

Does Fast Fourier Transform come up in Olympiads often or at all?

I've noticed that the blogs getting on the TOP tab on codeforces aren't necessarily the most upvoted ones.

I'm sure there exists a more complicated algorithm, but it seems to be based largely on the number of comments that a post has. This means that more controversial, stupid or someone started an argument in the comments posts which get people to comment will rise rapidly to the top.

What does the Codeforces community think about this? How would you change it?

Hello Codeforces, a lot of people have been asking me "How do I get GF!?". Well, I'm here to answer this question once and for all.

1. Reach Expert

Until I have reached expert, no girl wanted to talk to me. Right after contest Codeforces Round #677 (Div. 3)(when I reached expert) my Instagram and Snapchat DM's were full of messages from girls asking me out, this will happen to you too.

Proof

But you can't only get the girl, you have to maintain her! Which brings me to step 2.

2. Maintaining Expert+

Once you reach Expert, you have to keep it, unless you want her to leave you for another expert. This can be easily done by 2 main ways

  1. Never participate on Codeforces again.

  2. Ask solutions from other people during contests.

PS: Make sure not to get higher than Candidate Master.

3. Keeping the Girl.

Ok, you are maintaining Expert, now you have to keep the girl attracted to you. Wavelength isn't going to do everything.

  1. Buy her stuff. This is a very important step to maintaining a girlfriend(Eg: Food and Purses).

  2. Teach her competitive programming, but make sure you have more rating.

  3. Fight every simp she has to assert dominance.

  4. No dates until marriage.

  5. Upvote this blog post.

4. Flexing on other CP-ers

What's the point of having a GF if you can't flex on single people? NONE!

Message every single one of your friends and tell them about your brand new girlfriend.

5. Enjoy Life
