The program offers 3 choices. We need to buy the flag which costs $1337 but we only have $100 available.

We can buy a fake flag which costs only $50. We are asked how much of the false flag we want. At this point, we try to put negative quantities, like “-2”. We check our bank account and see that we’ve earned $100. All we have to do is set a higher negative value.
