Okay, this is for div2 coders like me. I have been using this trick, most of you must be already aware of it so this is for those who wait for 5min to see most number of submission and then attempt the very first problem.
So what I do, I basically open both tab div1 and div2 then see which questions are non scorable for div1 coders and then I solve those 2 problem. I have been using this trick , and believe me this work every f*****g time.
I don’t know why I am writing this, I think I should not tell this to anyone in order to solve faster than other or may-be I am on a trip.
Thanks me later.
