Steps I Took

Q1 & Q2 — Googled the first line of the code: object Flag extends App {. Results pointed to Scala. The second answer, App, was visible directly in that same line.

Q3 — Had no idea how to reverse-engineer the flag value. Asked Claude.ai — it got it wrong the first time.

Told it to try again and it got the correct answer. Two CS students also looked at it and couldn’t figure it out either.
