> AlphaCode's solution the "inner O(n) loop" is actually a memmove(), which is optimized to be insanely fast.
Again, it is not. CPython does not do these things.
The web page says, and this is corroborated in the paper,
> Solutions were selected randomly, keeping at most one correct (passes all test cases in our dataset) and one incorrect sample per problem and language. Note that since our dataset only has a limited number of test cases, passing all tests we have cannot completely rule out false positives (~4%), or solutions that are correct but inefficient (~46%).
The “54th percentile” measure did use estimated time penalties, which you can see discussed in Table 4 in the paper, but 1553D was not part of that.
