C++23 when
Come on guys, please check problem statement,i left the contest about 15 minutes in when i'm unable to solve Div1C ,later found out that it was incorrect.
very sorry for the mistake :(
Your perception of the difficulties was not exactly spot on...
Yes I also found the problems difficult but thought it was my skillissue :( sorry for the experience
My experience was relatively fine since I did Div1D (Defeating Monsters) first, but Div2 people must be far less happy with the difficulty gap.
Upd: it's not your fault that there aren't enough testers.
isn't the checker supposed to strip trailing whitespaces in the output ?
I am not able to get why my solution is giving WA on Div-2 (problem c) , can anyone give a Countercase for my solution, it will be really helpful

what will be the rearrangement and how , like I can see just 3 segments of 00 ,10, 10
10, then 00, then 10, resulting string is 100010.
ohk thanks got it
Can someone help me in Problem XOR And Multiply
when i used (1LL<<32), i got correct answer , but when i used that power function which calculates power in logn time , i got wrong answer. I think the TC of 2nd solution was sufficient to pass all the test cases
Correct Submission Wrong submission
Your power function has mod in it
ohh got it, i didn't focus on it
am I the only one or was the difficulty gap very high between b and c.
