It is the same as i++, am I right ? The difference lies in the timing of when the increment takes place=20 (immediately in the case of i +=3D 1, and after the value is used in=20 the case of i++). Do you think the distinction mentioned makes a=20 difference for the algorithm ? >=20 > You can replace that `while' with a for loop using` cl-loop' > and for, to make it a closer match to the pseudo-code. >=20 > This: (setq j (1+ j)) can be replaced by `cl-incf' as in > (cl-incf j) - but better yet is to get away with that and use > a for loop to iterate instead. >=20 > Again you can check out these two >=20 > https://dataswamp.org/~incal/emacs-init/perm.el > https://www.emacswiki.org/emacs/StringPermutations >=20 > but after spending so much time on your own solution I get it > you want to complete it ... >=20 > -- > underground experts united > https://dataswamp.org/~incal
