HDU 3940 the Angry Birds physics

// Conclusion: you should think about it right away. Don't hesitate there. Let's push some shit formulas ,. ..
// Click one .. Otherwise, the time will be exhausted .. That's it ..

// Take a physical formula and clarify the requirements of the questions step by step .. The question shows the flight modes of the three birds, and then calculates the flight distance ..
