This uses the <code>next-permutation</code> word from the <code>math.combinatorics</code> vocabulary. <code>next-permutation</code> wraps around and returns the smallest permutation after the largest one, so the only thing we have to do is check if we're at the largest permutation and return zero if so. See the implementation of <code>next-permutation</code> [https://docs.factorcode.org/content/word-next-permutation%2Cmath.combinatorics.html here]. |
