Take a look at the tags on this problem:

FFT? DP? bitmask? is this an inside joke that im not getting? why does it seem like for every problem most of the tags are completely fake?

I saw this blog post about requirements to create a contest. My question is, is the requirement still to be 2100 at one point? The reason I ask is because I've seen wonderful Div 2 contests hosted by purple and blue people, and I'd like to try my hand at problem making sometime in the future.

yay im cyan
