However, I got accepted.

strange

??? the problem says "No line will have more than 100 characters."

Thanks a lot.

it got accepted.

there's this bug in my program.

when you do the big shift, you have to have brackets around it

for example:

1+(2<<2) is different from 1+2<<2.

Strange.

anywayz, thx

#include<iostream>

oh, that, it worked on my computer,

I think I had to incldue

#include<algorithm>

for the header file.

But still, the judge gives me Wrong Answer after I put it on

Jan, I got all the output right, and I tests many cases on my own, the judege still tells me I get the wrong answer.

Here is my source code


#include<iostream>
#include<fstream>
#include<string>
#include<vector>
using namespace std;

//ifstream cin ("haha.txt");

struct card
{
long long num ...

I keep getting wrong answers.
Is there any tricks to this problem?

all I did is go through all the points and search for all directions.

anybody solved this problem yet?
the hint is useful, but I don't know an efficient way to code it,
can anybody help?
thx
