Interpreting the puzzle and figuring out the input record

Okay, the puzzle involves a sequence of attempts to enter a code of "0123456789." The record of attempts ends with the correct input, but it’s unclear exactly how the attempts are represented. There might be a string or log of failed attempts and backspaces, with the last one being correct.

Figuring out the attempt sequence from recorded digits

I’m considering if the sequence of attempts is just the final digits pressed before reaching the correct code. One idea is that he enters “0” first, then “01,” and so on, until the full code "0123456789." The sequence might be recorded as one long string, with each attempt’s input followed by a terminator.

Considerations on sequential attempts and code logic

I’m wondering, the record of all attempts might be the increasing sequence: "0", "01", "012", and so on, with each attempt being checked for accuracy. If he's using brute force starting from "0000000000," the final attempt is likely the correct "0123456789." It's possible that he knows the code but not its exact order!

Understanding the attempt sequence and final code

I’m considering that the recording of failed attempts might be a string of all digits pressed, leading to the final code "0123456789." If that’s the case, the total digits would equal the code's length, suggesting he succeeded on the first attempt. But then again, maybe there's a trick with the code starting at 0, so the first attempt could be empty?

Interpreting the puzzle with the final code

The puzzle might be asking about a record of attempts that ends with the correct code "0123456789." Since the record isn’t provided, I wonder if it’s implied that the string mentioned, "0123456789," represents both the code and the recording itself. This would suggest that the correct attempt is the last one—when he enters the full code.

Figuring out the first attempt

It looks like the recording consists of all attempts concatenated, with the final digits "0123456789" being correct. If the total length is only 10 digits, the first attempt would be the correct one. The answer to "which attempt was correct?" seems to be the first one, so I’ll go with attempt 1.

Ответ

С первой попытки.

Если запись всех попыток — это строка 0123456789 и она заканчивается правильным вводом, то других вводов до этого в записи просто нет (длина записи = длине кода = 10 символов), значит правильный код набран сразу.
