Code Quality and Maintainability | Dataford Interview Questions

How do you ensure code quality and maintainability?

Implement flag_long_lines(lines, max_length) as a small, readable quality check. Input is an array of strings and a non-negative maximum length; output is an array of zero-based indices for lines whose length exceeds that limit. Keep the behavior deterministic and easy to test.

Constraints

0 <= lines.length <= 10^4
0 <= max_length <= 10^4
Each line contains at most 10^4 characters
Return indices in ascending order

Function Signature

def flag_long_lines(lines, max_length):
