How to submit code to that shit site?
This Java code seems to work, but I don't know how to submit there:
package org.onlinejudge.uva;
import java.io.File;
import java.io.PrintWriter;
import java.util.Scanner;
public class ATheTrip
{
static Scanner in;
static PrintWriter out;
public static void main(String[] args) throws Exception {
in = new Scanner(new File("src/org/onlinejudge/uva/sample.txt"));
out = new PrintWriter(new
File("src/org/onlinejudge/uva/sample-output.txt"));
int T = in.nextInt();
while(T > 0) {
double sum = 0;
double netCost = 0;
double[] costs = new double[T];
for(int i = 0; i < T; i++) {
costs[i] = in.nextDouble();
sum += costs[i];
}
double ma = sum/T;
for(int i = 0; i < T; i++) {
double x = ma - costs[i];
if(x > 0) netCost += x;
}
String sNetCost = "" + netCost;
int dot = sNetCost.indexOf('.');
String decimalPart = sNetCost.substring(0, dot);
String fractionPart = sNetCost.substring(dot+1,
sNetCost.length()-1);
if(fractionPart.length() == 0) fractionPart = "00";
else fractionPart = fractionPart.substring(0, 2);
out.printf("$%s.%s\n", decimalPart, fractionPart);
T = in.nextInt();
}
in.close();
out.close();
}
}
