hey, i was solving an a2oj problem link : https://a2oj.com/p?ID=157 and when i tried to submit the solution it didn't submit after searching i knew that the website maybe don't accept submission anymore ( maybe i am wrong) can i find this problem in another oj so i can run my code on it?
A2OJ is dead as of now. I recommend you to use its codeforces ladder section to find problems for practice according to your rating :)
Arugo is a new site that I recently across and I find it to be somewhat useful for random problem practice sessions.
