Dropsort , conçu par David Morgan-Mar, est un exemple d'un "algorithme de tri" à temps linéaire qui produit une liste qui est en fait triée, mais ne contient que certains des éléments d'origine. Tout élément qui n’est pas au moins aussi grand que le maximum des éléments qui le précèdent est simplement supprimé de la liste et supprimé.
Dans cette tâche, vous recevrez une liste d'entiers en entrée (STDIN ou argument de fonction, vous devez prendre en charge au moins la plage des entiers signés 8 bits.) Votre tâche consiste à les triper, puis à afficher les éléments restants dans ordre.
Vous pouvez supposer que la liste est non vide.
C'est du code golf, donc le programme le plus court gagne.
