I disagree. The part

n being given (n integer, 1 <= n <= 50) calculate enum(n) i.e. the partition of n

is given just to explain the tests procedure. Those who in your opinion don't calculate the partitions explicitely calculate them anyway, because I am very doubtful you can pass the tests without calculating the partitions. Otherwise I think you can publish an article about it :)

duplicate issue.

It depends whether you call some spaces part of a column or part of a column separator. Some parts of this kata are tedious. Only by working through examples, the intricacies of the spec become fully clear.

second and first column are separated by 3 spaces when there are more than 10 players

Not really, the first column only takes more space in some cases.

only titles are centered, the numbers are Right aligned

The description says (I emphasize):

The column headers for the rank (#) and for the rounds are right adjusted, Players is left-adjusted, Pts and SB are centered.

So not a kata issue, I guess (but I let a more experienced user close this one).

programming is very math though

You're right, some tests follow the specs, some doesn't

expected:

see above (answer to see the message)

I made some changes here and there (all in the Molecule class description). They'll hopfully clear the air a bit...

mmmh, I see, ok.

And found out experimentally that carbon number is an index of the atom in the branch

could you give me a concrete example of this? I'm not following you, there.

(I should do a new sweep on the description, maybe)
