Thank you . . for the hint....

I am really disappointed by the test data, and i wonder how can the first person get this problem accepted.

I submit a program that output nothing, and got accepted with runtime = 0.00s.

The test input contains charactors besides 'A'..'Z', 'a'...'z', '.', ' ', ',', '-', '$'.

So bad this question is!

After about 10 submission, i finally get Accepted(PE).....

My observations:
1. input speeds are greater than zero
2. there is always solutions that lead your plane to fly along the desired direction, although you may flying backwards. (consider the set of data '100 270 0 1', you can never fly the ...

Try this test case:

9
0 1
5 0
4 1.5
3 -0.2
0 -1
2.5 -1.5
0 0
2 2
6 0
0

This should give probably:

Region #1:
(0.0,1.0)-(2.0,2.0)-(4.0,1.5)-(6.0,0.0)-(2.5,-1.5)-(0.0,-1.0)-(0.0,0.0)-(0.0,1.0)
Perimeter length = 15.16


Also, it seems that there is no cases for number of point <= 2 (i use the code ...

Finally, i find that the problem my program is integer overflow...

Dear all,

I have a hard time doing 714. I have tried many test cases and get correct answer. However, the online judge still reply 'wrong answer'...

Can anyone give me some hints about what points i have missed?

Thank you in advance.
