A school IT staff manages access to secure files by the method of access code. You are required to give your name and the access code, and the program will give out secret information.

It checks whether you already have an access code, generates new random one along with a new user ID alloted to the user, if that user is not found locally on the system. The access codes are known to have random expiration time (don't know what goes on in their minds!), so don't be surprised if you generated an access code just seconds ago and next time the same access code doesn't work.

Johnny decided to go into the IT room and copy the program into his pendrive. You can find it here.

Can you get the secret information out from the program? The service runs on 34.216.132.109 on port 9094.

Constraints

User ID / UID will be a positive integer

Output Format

Codefest{~flag~}
