Can you please have more rated contests for Div2 and above? I really want to participate in the short challenges but I really don’t know how for the past 2 months I have been trying, something just comes up at the time of the contest and I had to miss it.

I am forced to write a comment here since CodeChef really does not seem interested in replying to comments on its own website. In the problem Fat Hut, could someone please explain why the setter's and tester's solution give different outputs for the following testcase, and which one is supposed to be correct?

      Mine, and the tester's solution as well! The setter's code says -1 though.
