    401 Vous disposez des fonctions
    402 <code>droite()</code>,
    403 <code>gauche()</code>,
    404 <code>haut()</code>, et
    405 <code>bas()</code>
    406 pour faire avancer le robot.
    407 </p>
    408 
    409 <p>
    410 Il faut maintenant écrire vous-même la fonction
    411 <code>u(<i>n</i>)</code>
    412 qui va faire faire un virage vers le bas
    413 de longueur <i>n</i> au robot.
    414 </p>
    415
