That seems like a nice, easy puzzle someone should be able to do on a whiteboard, but I think it would work better on a computer -- my first iteration of this included a bug, as well as some print statements intended help detect and diagnose bugs. I could carefully think through the problem to ensure I get all edge-cases/bugs, but I do better playing with it interactively. (In this case, my first iteration included 'BC' and 'C' as substrings each occurring once.) You see my process better if you watch me write and correct this program on a computer. If my tasks is to think up a fully correct solution without iterative trying incorrect solutions, you're missing an important part of my process, even with a trivial FizzBuzz. (Though with this one you could probably just act as the interpreter and point out the errors for me.)
