Une façon simple de dissimuler un message consiste à décaler toutes les lettres qu’il contient.
Tu es face à un mot crypté avec le code César, tu dois trouver le mot de départ.
Tu as à ta disposition le mot crypté et le décalage effectué (décalage effectué sur le mot de départ).
Si le mot crypté contient un « d » et que le décalage est de 3, alors la lettre originelle est le « a ».
Tu dois retourner le mot de départ complet pour réussir le challenge.
