# UVA 11507 – Bender B. Rodríguez Problem

There’s really no need to attempt to code super simple programs more efficiently. Don’t be afraid to write a bunch of if-elses!

```import java.io.PrintWriter;
import java.util.Scanner;

public class P11507 {

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
PrintWriter out = new PrintWriter(System.out);

while (sc.hasNextInt()) {
int L = sc.nextInt();
if (L == 0)
break;
L--;

String ans = "+x";
for (int i = 0; i < L; i++) {
String input = sc.next();
if (!input.equals("No"))
if (ans.equals("+x")) {
ans = input.toString();
} else if (ans.equals("-x")) {
if (input.charAt(0) == '-') {
ans = "+" + input.charAt(1);
} else {
ans = "-" + input.charAt(1);
}
} else if (ans.equals("+y")) {
if (input.equals("+y")) {
ans = "-x";
} else if (input.equals("-y")) {
ans = "+x";
} else {
ans = "+y";
}
} else if (ans.equals("-y")) {
if (input.equals("+y")) {
ans = "+x";
} else if (input.equals("-y")) {
ans = "-x";
} else {
ans = "-y";
}
} else if (ans.equals("+z")) {
if (input.equals("+z")) {
ans = "-x";
} else if (input.equals("-z")) {
ans = "+x";
} else {

} else {

}
}
}
out.println(ans);
}

out.close();
sc.close();
}
}
