Usually, I use mirror sites m3.codeforces.com to play the contest, see problems and submit. But this it shows "The statement is not available" for unknown reason.

I haven't been informed that, so I play the contest use the main sites codeforces.com. But it continually requires to verifying if I am human when I submitted a solution, and it's been a little long, 2 to 5 minutes every time. This causes me to submit my solution 2 to 5 minus late in F and G, and more importantly, I couldn't submit E in the end of the contest.

I don't care about the result or the place, but it really made my experiences bad. I would very much like to know immediately if my solution of E is correct.

I don't think anyone would want to face such an issue.

I really hope this post can be seen and this issue can be resolved.
