                    We've set up our operations on a private island – and before you ask, no, not THAT kind of private island.
                    You've joined just at the right time – the first game of Red Light, Green Light finished and we've generated some fresh data to analyze and fresh bodies to harvest.
                
 
                
                    Your first challenge begins now: 
The organizers want to identify vulnerable living players who might be easily manipulated for the next game. Find all players who are alive, in severe debt (debt > 400,000,000 won), and are either elderly (age > 65) OR have a vice of Gambling with no family connections.
                    Show us how you handle our data, and remember – in this game, there's no room for error.

Think about how to combine multiple conditions using OR/AND operators. Boolean logic!
Break down the criteria into two main groups: mandatory conditions (alive, debt) and optional conditions (age OR gambling/family status)
