I Can view the solutions of past inoi problems

Hello guys, I am a newbie here. I have 2 questions:

  1. I was just checking the contests page where there is a contest on Past INOI problems (Code = INOIPRAC). But I can view the solutions before I have solved it. Does CodeChef allow us to view the solution on an ongoing contest?
  2. Does our rating increase if we solve problems in the practice section or it increases only when we compete in contests.

I hope I am not disturbing anyone.
Thank you for reading my question.


  1. You cannot view solutions for an ongoing contest, but you can view solutions for past contests or practice problems.
  2. Your rating only increases in solving problems in contests.

I hope that solved your query. :slightly_smiling_face:

Thank you so much.
But referencing to my question 1. The Past INOI problems is an ongoing contest, right? then why are their solutions viewable.
Sorry to bother you again :sweat_smile:

It’s an unrated contest.


INOI contest won’t give you any rating points, so it won’t really matter
these problems are actually kind of like practice anyways
Codechef allows you to view solutions in INOI, ZCO, etc. live contests, but not in long challenges, cook-offs or lunchtime

also, even though solutions are available, one must try the code themselves and NEVER copy-paste without actually understanding how to solve the problem!

hope it helps.keep coding :+1:!
