Day 13 was one of my dead-ends.  Couldn't get my head round it!
I did try ordering,  though I forget how,  and didn't get the approach to work.
anyway!

I thought I could understand day 14 quite well,  but couldn't see
what was wrong with my code!

Have at last finished the rest.  Day 25 was traditionally (?) easy; day 24 took
me ages to find a nice model.

Really "Chat" again - sorry!

Cheers,

Mike

Raul,

Yes, your example and its explanation are correct.
I'll rethink this approach, perhaps as you suggested.
