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.
The 10 in digits is for storing all possible digits (0..9), and each key stores the number of ocurrences of that digit in n
Nice recursion!

In my humble knowledge, I don't think there is O(26n) in Big-O notation. O(k*n) = O(n)
Okay then, thanks for explaining it.
Why would anyone read these comments before trying to solve it???

Didn't know how to rename groups and I didn't even think of www3., nice.
Sorry, I don't know what happened. I tried to repeat the problem, but this time, it didn't give me any error. When I was solving it, the compiler was sending that message everytime on 'Test' mode.
My code passed, but in tests, it keeps generating this error:
In file included from main.cpp:5:
./preloaded.h:6:82: error: no member named 'str' in 'std::basic_ostream'
return (std::ostringstream() << '{' << x.first << ", " << x.second << '}').str();
Why?

Didn't know this model of function definition. Thanks!
I didn't even think of using recursion, it's beautiful.
