for (int j = 0; j < soup.length; j++) {
salida += " " + soup[i][j] + " ";
}
salida += "\n";
}
for (int i = 0; i < soup.length; i++) {
for (int j = 0; j < soup.length; j++) {
if (i+j==soup.length-1) {

salida += soup[i][j] + " ";
String palabra = "";

if (intro.equals(salida)) {
palabra += intro;
salida += palabra + "este";
//System.out.println(salida.indexOf(j));
}
}
}
