Clarify the Problem Before Coding

Rewrite inputs/outputs, edge cases, and constraints in your own words—no code until the spec is crisp.

Try this in Python

spec = {"n": int, "array": list, "goal": "max subarray sum"}
print(spec)

Key takeaways

• Ask: uniqueness, modulo, time limits.
• Sketch tiny examples the statement forgot.
• If still vague, state assumptions explicitly in comments.
