I got -3 on a question and need help understanding why. As far I understand, I provided all the steps required to replicate the issue. I pointed out where the problem gets me stuck, as well as where I'm confused switching to trial-and-error.
Apparently, it wasn't obvious to at least 3 readers that it's a good content (and/or I'm missing something important in my diagnostics due to ignorance, hence failing to create a MRE).
Please advise.
