Hi y'all, I got AC on today's D 1870D - Покупка префиксов by a way different from the tutorial. I think my solution was very cheesy and am looking for a hack testcase that can WA/TL my solution here 223910585!

Thanks in advance!

    in fact, if you do your cheesy solution with 12 times instead of 5 times, it's probably gonna AC in all testcases

    The submission was hacked after the contest. Div.1 and Div.2 round don't have an open hacking phase and thus, this hack made after the contest does not change the verdict.

        It works in exactly the same way as hacking during Div.3/4 open hacking phase. But it's only availible for users rated $$$\ge 1900$$$ (iirc).
