Your edge case when n = 0 is incorrect - the description does not mention that you should return NULL in this case. In fact you should return the empty string (why?)
Your malloc()ed buffer does not account for the number of times n the string is repeated so it is often too short to contain the result
A malloc()ed buffer contains garbage values by default so you need to initialize it properly before performing string operations on it such as strcat()
I have apparently incorrectly assumed that the tests were the same because of the name and I admit it did not even occur to me to print the input. I also did not know I could see the tests after solving it. Thanks for the response.

The description "forgets" to mention that you need to return a freeable array.
Yup, you read it right: Dynamically. Allocated. Array. Of. Size. Three.

No extra variables! just the arrays passed.
nice ! It will not need math.h
Issues and question are not mutually exclusive.

The tests are fine, your code is not. Check how you validate the input values.
