Routing in Multilanguage website

I solved it in following way:

Put this at the end of the routes.php

PHP Code:

$route['^(\w{2})/(.*)'] = function($language, $link) use ($route)
{
    return isset($route[$link]) ? $route[$link] : $link;
};
$route['^(\w{2})$'] = $route['default_controller']; 


Please share if you have better solution
