I get the same thing

Thank you.
Of course. That makes sense :-)

what is the "int* lg" for?

int* lg is a pointer for returning the output array size.

And how do I return the array at the end?

Allocate memory, fill up the array with correct data, and return it.

I'm trying Directions Reduction kata in C but I'm still new to this language.
On this line:
char** dirReduc(char** arr, int sz, int* lg)
what is the "int* lg" for?
And how do I return the array at the end?
I'm creating a new array, allocating memory, placing the answers in the slots but when I return, the program's console tells me my array is empty.
I tested this solution outside codewars and in seems to work.
Thank you
