I failed in the test#3 many times.But i think my program is right.who can tell me the data of test#3?

I've accepted.I'm so careless."The segment of numerical axis from 0 to 10**9 is painted into white color.".I saw the axis is from 1 to 10**9 at the first time.so i failed in the test#3 many times.

Thank You So Much....
