Dependency Injection Refactor | Dataford Interview Questions

Refactor the piece of code. What is dependency injection, and where would you apply it?

Implement the refactored function process_values(values, policy). The injected policy is a dictionary containing minimum, maximum, factor, and offset; keep values within the inclusive range, then transform each retained value using the injected settings. Return the transformed values in their original order. Explain how injecting the policy improves testability and where dependency injection should be applied.

Constraints

0 <= len(values) <= 10^5
Values and policy parameters are integers
minimum <= maximum
The policy contains minimum, maximum, factor, and offset
Return values in their original order

Function Signature

def process_values(values, policy):
