SORRY IF IT DISTRACTED YOU ! AND THANK YOU TO ALL KIND SOULS FOR HELPING !

recently in hello 2026 contest, i solved problem B during the contest , which took me 2 hours almost (i am newbie afterall ) and during the contest i was going through it again i felt it may have passed pretest but it may fail on system testing so i added one more line of code which is this : if(op==0) break;

you can check my both submissions as well :

submission 1)

time = Jan/07/2026 20:17 (acccepted)

submission 2)

time = Jan/07/2026 20:14 (this one got skipped)

it is soo sad to see getting a solution skipped when u gave it 2 hours to solve :( ,

i dont know whom to address so i am writing a blog i hope it may reach to the right person ,

kindly check it out [user:MikeMirzayanov][user:KAN] and if you know whom to contact please let me know , and sorry if my blog disturbed you, im just idk sad cause of this, sorry again if it distracted you

edit_ FOR THOSE WHO WONDER HOW I SOLVED HIGH RATED PROBLEM : FIRST, ITS AFTER THE CONTEST , AND SECOND I READ THEIR EDITORIALS , ALSO https://mirror.codeforces.com/contest/702/problem/E this is one the problem i solved 2000+ rated, its 9-10 years old problem , you may wonder that why i was studying binary lifting ?because there was recently a binary lifting problem in atcoder beginner contest (problem link — https://atcoder.jp/contests/abc438/tasks/abc438_e ) date- 2025/12/27 , so i was studying this concept and solving related problem then i found this 9-10 year old problem from codeforces on binary lifting :) its a fundamental problem of binary lifting :) , YOU MAY CHECK all high rated problems are those which i solved after the contest or are very old problem , during contest i barely solved 2 problems :)

It showed Skipped because it only counts the last AC submission, the reason was not about cheating.

    It's a binary lifting problem brother , and it is very old too , also if you have seen that problem it's very straightforward,just the direct use of binary lifting :) ! Thanks for your time though
