### USACO Problems

Número de respuestas: 0

I am trying to setup USACO problems in my Moodle Open source code runner. I do not know how to specify the file input which is given by one of the students in the solution.

import java.util.*;
import java.io.*;

public class billboard {

public static void main(String[] args) throws Exception {

Scanner stdin = new Scanner(new File("billboard.in"));

// Mark both seen billboards.
boolean[][] see = new boolean[2001][2001];
for (int i=0; i<2; i++) {

int x1 = stdin.nextInt()+1000;
int y1 = stdin.nextInt()+1000;
int x2 = stdin.nextInt()+1000;
int y2 = stdin.nextInt()+1000;

for (int x=x1; x<x2; x++)
for (int y=y1; y<y2; y++)
see[x][y] = true;
}

// Mark squares that can't be seen.
int x1 = stdin.nextInt()+1000;
int y1 = stdin.nextInt()+1000;
int x2 = stdin.nextInt()+1000;
int y2 = stdin.nextInt()+1000;
for (int x=x1; x<x2; x++)
for (int y=y1; y<y2; y++)
see[x][y] = false;

// Count which ones can be seen now.
int res = 0;
for (int i=0; i<=2000; i++)
for (int j=0; j<2000; j++)
if (see[i][j])
res++;

// Ta da!
PrintWriter out = new PrintWriter(new FileWriter("billboard.out"));
out.print(res);
out.close();
stdin.close();
}
}
Can someone help me please to set up one general template in my code runner setup?
