Exercise 9:
Distributeur de billets en Python
Il y a un guichet automatique qui peut distribuer des billets de 100 dollars, des billets de 50 dollars et des billets de 20 dollars. Écrivez un programme en Python qui reçoit d'abord le nombre de billets disponibles. Ensuite, les clients retirent leurs montants souhaités en fonction des billets disponibles et chaque fois qu'un montant est retiré, le nombre de billets disponibles est équilibré. Si le montant ne correspond pas aux billets disponibles, le message d'erreur s'affiche pour le client. Si le guichet automatique est à court de billets, un message d'excuse s'affiche et le programme se termine.
