> Spaced repetition is great for rote memorization of arbitrary facts

Traditionally, yes. But several people use the SR algorithm to simply do the same problems over and over (practice), without the memorization component.

Looking at a typical SR algorithm, you're not really going to memorize doing the same medium/high Leetcode problem unless you actively try to memorize it. The interval sequence will be something like: 2, 5, 13, 35, 120, etc. By repeatedly solving the problem so few times in such a long period (and while solving other problems at the same time): You're not really going to memorize it accidentally.
