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.
Thanks for teaching me something new :)
Hello!
By details of this kata we must sum up the CUBES of digits.
I think you need to fix it here "sum += Character.getNumericValue(num);"
However, it is great solution
It only works when the variables are the same type. e.g. here
iandjare bothint.Hint: It pays to re-visit the language spec sometimes. There are lots of little things that are useful but maybe you don't see them much in common use. Do it now. You will quickly learn something else you didn't know about...
I did not know about that you could use two different variables in the for loop like that. You will have a better coding career than me. Props
Not sure what you mean... It's just common syntax

How did you learn to code the for loop like that?
