There's a bunch of better ones that are readily accessible. Ask the candidate to build a known quantity like say, a calculator, calendar, whatever or give them a bunch of code and have them modify it in some way or discover a bug. Something closer to building software. Leet code is too far away from it and the performance on it too poorly correlated with actual suitability.
