December 2012 Bronze Problem 3: Crazy Fences

Result: 0/10 xsxssssssx (why were there signals?)

I have given up on this one. As a result, I just submitted code that will return C, in hopes that no boxes are formed by the fences for as many test cases as possible.

crazy.cpp

#include <iostream>
#include <fstream>
 
#define loopi(x) loop_start(i,x,0)
#define loopj(x) loop_start(j,x,0)
#define loop_start(i, x,s) for(int i = (s); i < (x); ++i)
#define loop_rev(a,x,stop) for(int a = (x); a >= (stop); --a)
 
using namespace std;

struct fence
{
 int x1, y1, x2, y2;
 // each fence is vertical or horizontal
};
fence *fences;

struct cow
{
 int x, y;
};
cow *cows;

int main() {
 ofstream fout ("crazy.out");
 ifstream fin ("crazy.in");
 // get input
 unsigned int N, C;
 fin >> N >> C;
 fences = new fence[N];
 cows = new cow[N];
 loopi(N)
  fin >> fences[i].x1 >> fences[i].y1 >> fences[i].x2 >> fences[i].y2;
 loopi(C)
  fin >> cows[i].x >> cows[i].y;
 // process
 // I give up...
 // output
 fout << C << endl;
 // cleanup
 fin.close();
 fout.close();
 delete[] fences;
 delete[] cows;
 return 0;
}
