Hi,
I was participating in Codequest 2.0 on Codeforces and had already registered through Unstop. I was able to enter the contest and successfully solved 2 out of 8 problems.
However, during the contest, I accidentally got redirected to another page. When I tried to re-enter the contest using the same link, I started getting the error: “You do not have view access to non-public contest.”
Even after logging out and logging back in, the issue persists, and I am unable to access the contest again.
Could you please check if my access has been revoked or help me regain access to the contest?

if you skip the condition for lex smallest then the h question was pretty standard question from kmp/zfunction and just bit added up more i thought my hashing will collide but instead i fked up vector reallocation part
the question that am refering to
808G - Anthem of Berland this is the first question that pops up when you learn string automation from cp algorithms
The B problem was a bit tricky, but the solution was super simple it was just this:
Even I was also trying some unnecessary dp stuff for a while and getting wrong answers when I realized that it is a very simple question. I think because of this question few Master rated people couldn't come in top 10 because they were unable to solve this one. Even Domminator took 4 tries for this question. Usually last questions decide the top players but this time I think B question became the deciding factor.
any update on results?
sorry for the delayed results, authors were a bit tied up this week!
