Am I missing something here? Assuming you're writing `char * fizzbuzz(unsigned n)`, can't you determine exactly how many bytes you need at the outset from `n` and just malloc once?
There are some variations of fizzbuzz that have you print out the number of iterations performed at that point on each line. The memory consumption could still be predetermined, but the math is a bit more complicated. Other variations have you reading integers from a stream (integers are not in any order), printing "Fizz" and "Buzz" when it's a multiple of 3 and 5 respectively, and that does not have a predetermined memory footprint.
While FizzBuzz has become notorious for weeding out total incompetence [1], there are some variations of the problem that are unexpectedly nuanced.
