Finally I got AC using Python . But I suppose input data may have garbage in the last (e.g. additional space), so length for every row input is NOT 3...

x is not unique.
So
input: output:

Thanks to Mehadi, your WA code active me write AC code.
But I still don't know what bugs in your WA code.

my WA code is here, why got WA???
could someone give me more test case and correct solution?
really need help..

PS. Finally I got AC, and remove my code, I think WA due to wrong blank line during output

Try the cases.

Input:


3
4 4
0 1 1 1 3
0 0 0 0 0
0 0 0 1 1
0 1 1 2 9

0

following is ...

change

Code: Select all

   if(x<y)GCD(x,y%x);
   else GCD(y,x%y); 

to

Code: Select all

   if(x<y)return GCD(x,y%x);
   else return GCD(y,x%y); 

Yes, you are right! thanks a lot!

solved!

why following code on-line judge compiler error? when I using following code, it's ok. I want to ask, when I using int main(),
what value should I return?return 0? or other value?
and why I can't use void main instead of int main?

hi~

I am trying to solve this problem but I keep receiving WA.

I really don't know why my solution doesn't work.

In the problem description,

Each SCUD missile (anitary leansing niversal estroyer) that lands within the walls of a kingdom destroys that kingdom's power plant (without loss of ...

Hi!

I am also trying to solve this problem...

I don't know what's wrong...

If SCUD hits the wall than is it counter as it hit the convex polygon or not ??

Could anyone who got AC tell me what is is output for this input:

4
0 0
1 1
1 0
0 1
4
10 10
