Give it an input and say what you think comes back. It compiles and runs for real, so a wrong guess still shows you the answer — probe as much as you like. Only correct predictions count.
Locked until you have predicted 4 outputs correctly.

| 6 | if (running < 0) running = 0; |
| 7 | running = running + nums[i]; |
| 8 | if (running > best) best = running; |
