Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

I did not really keep track of time, but I guess it took me 2-3 hours.
May I ask how long it took you ?
Yup, just realised. Guess my solution needs more work :)
Thanks for the reply!
Hi,
There are no inputs like these. The actual inputs are:
"{[Co(NH3)4(OH)2]3Co}(SO4)3"
and"(C5H5)Fe(CO)2CH3"
The formulas "C5H5)Fe(CO" and "NH3)4(OH" should cause an IllegalArgumentException to be thrown, shouldn't they?
To me they don't qualify as valid formulas and I don't see how they should be valid given the description.
Yet those test-cases fail if an exception is thrown.
