it acctually should result in 0. Here is the step-wise calculation:

Step 1: 4//9 = 0 (since, as per the specs, we are supposed to apply integer division to stay on a "happy path", so 0.444 would become 0)
Step 2: 3*0 = 0 Voila!

However, any which way you would get stuck with some other errors, since the evaluation logic sometimes applies rounding instead of the expected integer division (see my comment above).
