Sample Explanation 1

It takes $ 2 $ hours to move from point A to point B, and $ 3 $ hours to move from point B to point C. Therefore, it takes $ 5 $ hours to move from point A to point C via point B. Since it is not possible to move within $ 4 $ hours and 30 minutes, output $ 0 $.

Sample Explanation 2

It takes $ 7 $ hours to move from point A to point C via point B. Since it is possible to move within $ 10 $ hours and 30 minutes, output $ 1 $.
