В условието сме написали следното:

В случай, че ви подадем буквичка, която не е една от тези, ще очакваме да panic-нете.

Проблема е, че ти не си panic-нал -- ти си напечатал грешка на стандартния изход и си върнал counter с нулеви бройки. Точките ти бяха 15, защото имахме бъг в системата за проверяване, за нещастие. Вече са смъкнати на 9, сори че чак сега се случва. Давам ти 1 бонус точка за корекция като компенсация, но за второ домашно чети условието по-внимателно :)
