I’ve recently started participating in the ‘CodeArena’ 1-to-1 fight. However, not a single opponent has ever managed to submit even a partially correct solution in any of the fights I’ve participated in.
Some days ago, while ‘fighting’, I saw my opponent compiling his code and then submitting it only to get a WA in all the test cases. The problem was far too easy to get a WA. I tried to locate his submission after the fight, but couldn’t find it.
My suspicion increased when I looked into their profiles. All of them “hasn’t added any details yet.” Each profile name has the syntax: <first_name><last_name>, sometimes followed by another and/or a random number.
I can not tell if every account is legit but I remember losing to an opponent once, I just missed some minor edge case and got WA in a few test cases, so after the arena fight ended I had a one-one to conversation with the opponent in inbox about what I missed.
Here is a screenshot of the conversation(I have hidden the name of the sender for obvious reason)

But then again this is just one case, I too have my suspicions for the exact same reason, of the matches I have played I lost only one of them and rest were either wins or draws(and this is considering that I am bad at Competitive Programming, so there is no way I could have won most of them). So, are those accounts legit or just some bots playing around? I don’t know but hope someone can put better insight.

I think there are some bots competing against us. I just looked into my fight history on CodeArena. I have had 9 fights till now and 6 of the opponents have their name as per the syntax you described. Also, I looked into the submissions on the problem page and their submissions weren’t there. Also, none of them has a profile picture and they haven’t submitted a single solution yet according to their profile. I have won 5 fights and all of them are against 5 opponents out of these 6. The fight against the remaining 1 out of these 6 was a timed out. For the rest 3 opponents, they have at least some information on their profile and their submissions even show up on the problem page. Also, none of those 6 opponents is following anyone but 4 of them have some real followers. Strange!
I can explain to you why so many of these people have <first>.<last>[integer] as their name. When I created my account on HackerEarth, I signed up with Google account. Apparently it automagically generates your name based on your Gmail account so mine also ended up in that format, and I didn’t bother looking to change it.
We do compete against someone many a times, cause I’ve competed against my roommate several times, a thing we do by simultaneously pressing fight button
Hey @sarthakmanna, I have been practicing problems on Hackerearth for the past few months and have had some one to one fights at the Code-Arena platform you are concerned about.
Me and a friend of mine managed to fight in the same game by searching opponents at the same time. So, all I can say is that the platform allows users to compete against each other for sure but I don’t know whether there can be a possibility of a virtual fight only.
Alright I am new to this competitive coding too, I don’t seem to understand how one should present the test cases, my method gives the right output but the during submission it says that the output doesn’t match even though when I try compiling it in my local IDE it works.
Is there some way to code the output so that the judge can understand it? please tell me i have been getting correct answers but it ends up not being understood??
I recently participated on CodeArena and I had passed all the test cases before the opponent but still I didn’t win the round . Instead out of 14 test cases, I passed 16/14 out of them . How is that even possible.

. How is that even possible.
