Welcome to Stack Overflow. Please read Open Letter to Students with Homework Problems and Why is "Can someone help me?" not an actual question?. You can't just dump your problem statement here and expect us to do it for you. It's also a good idea to take the tour, read about what's on-topic in the help center, and How to Ask. — Chris 9 secs ago
