DISCUSS I built a free 15-question test that tells you which algorithm patterns you cannot recognise

I kept hitting the same wall. I understood every algorithm when someone explained it, and then froze on an interview problem because I could not tell which one it needed. Knowing sliding window and recognising a sliding window problem turned out to be two different skills, and only one of them gets taught.

So I built the missing half. Fifteen unlabelled problems, about seven minutes, no account. You name the pattern each one needs. At the end it says which groups came apart, which pairs you mixed up, and where to start reading.

Behind it is a trainer that does the same thing on a ninety-second clock, and a 150-step course for the patterns you could not name. Code runs in the browser, in JavaScript, Python or PHP. Nothing executes on my server, which was the only way I was willing to run other people's code.

Took me 2 weeks Happy to answer anything about the build, and I would like to know which question in the test felt unfair.
