It's the strict performance requirements (tests will fail if they take more than a few seconds) and the short time limit to make the solution that make it tricky. My suggestion: type up the project description in a separate window and feed it into AI. Or at least start off by thinking of the trickiest, most non-obvious ways to solve the problem. Definitely a frustrating experience. Note that if you do not successfully complete ALL automatic test cases, your submission will be immediately, automatically rejected without any human ever looking at it.
