    it's prewritten, so it can be fast. and also, it's really goofy so it needs to stay simple enough for people to understand -> fast editorial

      False. I once got the output:

      wrong answer "Procrastinator"? Procrastinator: Someone who keeps delaying things that must be done.

      And I was wasting my time with the wrong problem, instead of any other. So I think I still fit the parameters ;)

What words trigger funny checker responses in D? I managed to get "no", "yes", "lie", "procrastinate", any string containing both "no" and "yes", and the easter egg.

Also, F is nearly impossible without a phone...

    I thought the task was to submit a QR decoder and managed to adapt some QR reader repo (that works on images) to be Codeforces-submittable and work on binary matrices: https://github.com/dpaleka/qr-reader-matrix. Of course, this would WA, because it doesn't produce "12" but "max 4x4 sum", lol.

    That means (almost) the same as megabytes. Kibibyte = 2^10 bytes = 1024 bytes, mebibyte = 2^20 = 1024*1024 bytes = 1024 kibibytes. However, in most cases binary prefixes (kibi, mebi, gibi...) are more correct, because standart SI prefixes, which are commonly used, mean another numbers (kilo- = 10^3, mega- = 10^6, giga = 10^9...)

In D, I printed JNybraNfNW which led me to the easter egg osnxymbjws. Then i printed osnxymbjws which led me to rvfqjqrfgp and asking to give up. Then i printed rvfqjqrfgp which led me to zcaziobjzu and asking me to leave suggesting that all these incorrect submissions causing me Penalty. Then i printed zcaziobjzu which led me to rymhtsgare saying that Fine, this is what you are looking for. Then i printed rymhtsgare which led me to ckkjqfhfrb saying that I have been Fooled. Then i printed ckkjqfhfrb which led me to xfbntvovfq. Finally i printed xfbntvovfq which again sent me to jnybranfnw forming a cycle.

For question D, assume you do not submit within the last fifteen minutes:

If the string you submit contains affirmative words, such as 'yes', 'sure', you will receive the reply: I have no reason to believe you.

If the string you submit contains negative words, such as 'no', 'never', you will receive the reply: Diagnosis: Skill issue.

If the string you submit contains both affirmative and negative words, you will receive the reply: So you are both a procrastinator and not? I do not believe you.

If the string you submit contains numbers or symbols, you will receive the reply: I am too lazy to learn how to read that character.

If the string you submit contains 'lie', you will receive the reply: I never lie.

If the string you submit is not a keyword, you will receive the reply: I am yet to download enough RAM. Give me short and concise responses that I can understand.

If the string you submit is too short, you will receive the reply: Your response is too short. I cannot bother replying if you do not respect me enough.

If the string you submit is too long, you will receive the reply: Your response is too long. I am too lazy to read all that.

It is important to note that only the first line of the string is checked; other lines of the string are not checked.

This content was derived from an hour of work and dozens of submissions.Crying...

Question for C

Since "The problem asks for the problem count of the April Fools Day Contest that was n years ago." why in the 1st example for input 0, so for the current year the answer is 10, if it's 12th contest.

Similar for the 2nd example, 1 year ago was 11th contest.

Man, I couldn't solve A because I was only looking for the green lights. Then I tried to take all pictures except for the ones with red lights or where the red arrow on traffic lights points to. Also, I was trying to get the answer counter-clockwise because there was a roundabout sign. After all that, I gave up and gave the picture to Microsoft AI

I submitted 'safety' without even knowing why, just because an AI told me to. So yeah I'm apparently a robot :D

Also, I was sure that the problem name suggests my solution is intentional, and I wondered why so many people had already AC on it.

I think the contest should be rated!! Of course, only for legendary grandmasters After seeing our questions, I said: Hey, tourist, where are you? Do you think you can still contest and complete?

Bruh do the numbers in E actually mean the number of mines in the tiles around it not including itself? I thought it included the tile itself and I got stuck trying to make sense of the samples lmaooo 😂😂🔥🔥 should've realized why the numbers do not exceed 2 instead of 3.

    I think I got this thought process because I was trying to solve it as if the grid consists of 2 lines, with the first line being array a and the second line being filled with unopened tiles.

I'm curious about response if one print "No" early. Who tried this, and what feedback did you get?

    I assume you mean "Yes". I printed it and got

    "Yes?" I have no reason to believe you.

        Oh. I printed Yes No once (actually, in hindsight, I don't know why I did that but whatever), but never only "No".

        EDIT: A person above submitted it, you can check what they got.

Mentioning the address of the earth within outer space in the header of problem [I] sounds pretty logical. ONLY aliens can solve it!

It seems that the codes of other contestants are not yet visible.

If visible, the numbers in the first column should be blue instead of black.

Does anyone else have a similar situation to me? Am I the only one who can't browse other contestants' codes? How to solve this problem? Thanks!

Seems simple enough.

    A real procrastinator should solve it in last 15 mins, I solved it in last 50 seconds. One of the best procrastinators out there!

I think that if G add the 1 0 testcase then it could have more ACs.
