Feb 4, 2014 at 10:51 comment added Mr.Wizard Please see the timings I added to my answer. In some cases your method is far and away the fastest method yet posted, when applied correctly. Well done.
Feb 4, 2014 at 10:33 comment added Mr.Wizard Notes: (1) If the lists that are assembled are short Insert is not expensive; this is a good method. (2) Because you Fold over lst1, lst1 should be the shorter of the two lists if there is one; this will be much faster than the other way around.

Feb 4, 2014 at 10:09 comment added Yi Wang Sure. You are welcome to edit!
Feb 4, 2014 at 10:08 comment added Mr.Wizard That is quite a clean method, and I see the possibility to make this code a bit cleaner still. May I edit your post with these changes? If you don't like them you can simply "revert" the edit to undo them.
