To be clear I am asking to hide the rating column from the problemset page, not the rating tag on the problem description page.

This is how it appears right now.

I would like the ratings here to not be shown.

I just read Problem F editorial.

I realise that computing the sum of the numbers in the box (when nothing is set to 0) is not very difficult. (Its just some interpolation of the sum of first n natural numbers). It becomes complicated when alternate values are set to 0.

In this editorial the answer has directly been provided and the explanation for the jumps in reasoning are skipped.

I was hoping someone could provide an explanation to fill in the gaps of this editorial.
Thanks. :)

As you can see in the image attached below. 5 weeks ago image turns to be 20.05.2003. I thought there was a problem with my computer but it seems other people are facing the same issue. Is this a codeforces bug?
