Challenge Description

It’s Sunday. The sun is shining, the beach is calling,
and someone decided to… write code?

That’s illegal.

This binary enforces the sacred rule: No work on Sunday. But something feels off… The program asks for a key, hides its intentions, and definitely doesn’t want you poking around.

Can you break the rules, reverse the logic, and uncover what’s really going on behind the scenes?
