## Code
# Monty subset python (no imports assumed)
nums = data["nums"]
total = 0
for n in nums:
    total += n
total

## Inputs (JSON)
{"data": {"nums": [1, 2, 3, 10]}}

## Output Expectations
Stdout prints the returned value.

## Risk Assessment
Risk level: low
Justification: Pure arithmetic over provided JSON data.
