The Most Wanted Letter

The Most Wanted Letter


On vous donne un texte qui contient différentes lettres anglaises et des symboles de ponctuation. Vous devez trouver la lettre la plus fréquente dans le texte. La lettre trouvée doit être en minuscules.
Lors de la recherche de la lettre la plus fréquente, la casse n'a pas d'importance, donc pour les besoins de votre recherche, "A" == "a". Veillez à ne pas compter les symboles de ponctuation, les chiffres et les espaces blancs, mais uniquement les lettres.


Si vous avez deux lettres ou plus avec la même fréquence, renvoyez la lettre qui vient en premier dans l'alphabet latin. Par exemple -- "one" contient "o", "n", "e" une seule fois pour chacun, nous choisissons donc "e".

Entrée: Un texte à analyser sous la forme d'une chaîne de caractères (string).

Sortie: La lettre la plus fréquente en minuscule sous la forme d'une chaîne (string).


assert.strictEqual(mostWanted("Hello World!"), "l");
