       J'ai du me tromper dans les initialisations
       Pourtant, la logique ne me semble pas fausse:
           On stocke le résultat dans y
           i est la variable d'incrémentation initialisée à 3
           à chaque tour, i = i-1 pour rencontrer la condition d'arrêt i = 0
           à chaque tour, y reçoit x*(x+1)
