Recently there has been mass hacking for quite some tasks on CSES like Inversion Probability, Fixed-Length Paths(I-II) and more.
Inversion Probability has particularly annoying new tests and (i think) an edited statement saying "(rounding half to even)". I have no clue what its supposed to mean, but luckily same idea but in python passed... for now.
Anyways at the time of this blog's making the task has only 84 solves, so if you caught an L on cses like the blog.
RIP Rainboy for losing #1.
Thank you for your public announcement, those new test cases for Fixed-Length Paths are truly awful.
