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.
Not an issue
Managed to?
This should be in the description.
i have met the same problem.... how to solve this ?
I think this walk will take you 8mins and not exactly 10 like the problem asks for
Same here, any ideas?
You didn't pass all the tests, sorry! You're missing an edge case, the empty string. It specifies in the problem description that the empty string should be counted as a proper group, and thus return true. I can't see your code, but I'm guessing that it assumes at some point that the string is non-empty, and grabs the first element, which of course doesn't exist if the string is empty.
Which language? The timing is sufficient but when codewars is too busy, it can time-out.
All is in description. Did you really verify your co-prime rule?

Could you propose a better description?
