Call for Participation

I couldn't stop looking into those enigmatic eyes. We were sitting next to the bar, facing the dancing floor. The party kept ongoing heavily as this was the last segment of the Mediterranean bachelor cruise, from Nice to Barcelona, and the dream-trip for those youngsters was going to end in about 18 hours. I had "e-met" this person the night before when I was hacking the cruiser's database to get the list of all the passengers and their profiles. I was bored. The system was poorly designed and an old exploit granted me access to what I needed. Once inside the system, I noticed that I was not the only person who had the same thought. The message "I was waiting for you." prompted into my terminal. "Who are you?" I asked, as I was curious to know who was the other hacker in this cruise. "My name is 'Z'." the other intruder answer. After a couple of exchanges we set an appointment to meet personally at the cruiser top level club. I had chosen a place full of people for safety reasons. I kept wondering who was this person the entire day. Finally the night arrived and I was sitting in front of 'Z'. "I have a project for you" Z said. "I am not interested" I replied immediately. Z took a small peace of paper out of the pocket and handed it to me: "Maybe this will interest you". There was a six digit number written in it. "What kind of project?" I asked. "First I need you to pass a test" Z answered. I didn't like where things were going, but my curiosity wouldn't let me back-off : "What test?" Z stared at the dance floor, those eyes again, the floor was full of young people chatting and dancing: "I need you to write an algorithm the takes the profile of everyone in this crowd and finds a good match for them. If every one has a match before we arrive to Barcelona, then I will answer any question you have". I felt like the paper in my hand was bursting into flames, it was starting to burn my fingers. The six digits were dancing in my mind. I finished my drink and I answered: "Game On!".
