A concrete starting point
Count integers from one through n that are coprime to n using Euler’s totient, with n capped at 1000000000. Check one, primes and repeated factors, rejecting zero, negative, fractional and Boolean inputs.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.
