Talk:Permutations/Rank of a permutation
Python: Recursions as iterations
Thanks spoon for making the change, but are we now too far from the Myrvold & Ruskey paper that the functions are based on? An alternative is too add your update as a separate set of examples, but that is up to you - I can go either way.
I do like your use of randrange. Neat :-)

- I have changed them back, but kept the unrankers as loops, but kept them as close to the original code as possible.
- By the way, the previous use of
randint
was wrong.randint(0, perms)
generates numbers from 0 to perms (inclusive), likerandrange(perms+1)
. --Spoon! 04:19, 27 October 2012 (UTC)- Ah, I understand that now - O read that about randint but failed to notice the significance, Thanks again. --Paddy3118 08:13, 27 October 2012 (UTC)
