We have prepared a set of Editor's Choice Solutions. You will see them first after you solve the mission. In order to see all other solutions you should change the filter.

Une médiane est une valeur numérique qui sépare la moitié supérieure d'un trié list de nombres de la moitié inférieure. Dans le liste (list) où il y a un nombre impair d'entités, la médiane est le nombre qui se trouve au milieu du liste (list). Si le list contient un nombre pair d'entités, il n'y a pas de valeur médiane unique, mais la médiane devient la moyenne des deux nombres trouvés au milieu. Pour cette mission, on vous donne un non vide list d'entiers naturels (integers). Avec ce tableau, vous devez séparer la moitié supérieure des nombres de la moitié inférieure et trouver la médiane.


Si vous souhaitez vous entraîner davantage avec le cas similaire, essayez la mission Middle Characters.

Entrée: Une liste (list) d'entiers (integers).

Sortie: La médiane sous la forme d'un nombre flottant ou d'un nombre entier.
