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.
Groovy translation
What is wrong with the Java translation that it's not merged?
That's an invalid input, and you've been told what to do with that:
Not a kata issue.
For C there is a test with count == 0, but the instruction was clear "the array can't be empty".

Your code fails for two reasons:

Think of it as a list of single-digit positive numbers separated from an integer. The output should be derived from merging them, incrementing the number by one and then separating each digit in the form of an array.

For C, the Attempt tests seem broken.
The following test I return *count = 0 and return a pointer to a zero-sized buffer ("RETURNING NULL").
1 2 -1
RETURNING NULL <-- my debug code
There are other tests that hit this code that accept this value, but this one doesn't. Seems like bug.
This kata looks straightforward initially but then you find out some clever constraints.
