Cool!! Back to Back dominator rounds.
binary string problems incoming
Contest starting in ~35mins. Good luck. We hope you enjoy the problems.
Can anyone provide a solution to resolve the 403 error? I'm using my college WIFI, although website works fine on mobile data(Codeforces).
I was getting forbidden error too while using my uni wifi
great problems
Were the testcase for problem A (Div-1) Bigdif changed? Since during contest I had a lot of wrong answers and not it has been converted to correct. Wasted a lot of time trying to debug it :(
Same here. There was no announcement as well. The round should be made unrated for the contestants who faced such an issue and got a negative delta.
The announcement says you will be given a choice to be unrated if your verdict changes.
Ig no negative delta for me then :) , though rated for 6 star happens only a few times so a bit disappointed :(
IceKnight1093 could you please look into this? The round still shows rated for me and I have not yet recieved a choice to become unrated as well. CodeChef handle: pradyumn1908
Same here. I guess the checker suffers overflow because I brute force all pairs from high to low.
I had the same approach, I guess that's why
What is your thought process on the problem "Smoothly Increasing"?
The difference of Consecutive elements grows exponentially, so it would be impossible for numbers greater than let's say 100. You can brute force for n <= 100
Actually the number is even smaller , we can brute force for n<=31. Just saying.
yes yes, 2^31 > 1e9, so yeah
Great Contest. Enjoyed solving REDPAL and CNTDISJOINT.
