  │   ├── ChallengeNameFactory.sol  # GGGG. factory to deploy and check the challenge

  │   └── Level.sol                 # interface. don't touch

  ├── scripts

  │   ├── deploy.py                 # HHHH. for deployment to the chain

  │   ├── exploit.py                # IIII. your solution and script to check if it's working

  │   └── pwn.py                    # utils. don't touch
