If this passes then idk for what the tester @raja1999 is being paid for 
@rishup_nitdgp @teja349 @admin
This is being very often now. I think admins should make some strict rules for testers.
In april long challenge STRNO test cases are weak.
I myself hacked two problems in may long challenge ( and reported in comments as well) (but the hack’s were not very trivial so refrained from reporting through email and discuss ). And test files of 3 problems were changed during contest.
I would like to request @rishup_nitdgp to update test files for practice section at least now.
