Can Unrated coders become setters? Or is the id wm101 fake??

I think you can become a problem setter by recommendation or having an ID elsewhere like on codeforces or Atcoder.

Hoping I’ll become a 6* after this or not 4* atleast

I am well prepared to lose my ratings this time :smiley: :P. But won’t see leaked solutions for once.

Is this a Codechef Long Challenge or a Mathchef Long challenge ?

True most/all of it is only maths.

Sorry all, but my Editorials for MOVCOIN2 and MVCN2TST will be delayed :frowning:

This is partly because these are my first two Editorials and I underestimated how much work goes into them, but mostly because I tried to do something … a little different, and it ended up taking up a bunch of time :slight_smile:

They’re in a state where they are useful though, I think, so I’ll be including links to HTML versions in this post and updating them as things get done; hopefully there will be links to drafts within the next half-hour or so.

I’m incredibly tired and fairly busy, though, so updates might takes a while XD

Edit: Wait, what - the Editorial threads have been made public, but they’re not ready yet XD

Edit2: I have no idea what’s going on, but here’s the current MOVCOIN2:

MOVCOIN2 Draft Editorial
MOVCOIN2 Editorial Solution

… and MVCN2TST:

MVCN2TST Editorial Solution

Edit3:

The official Editorial threads are now the ones you should be reading :slight_smile:

Simon, I think the editorial already contains many ideas that will be helpful to most contestants. We decided to make it public, so contestants can also discuss the problem. Is fine to update it when you have more time.
