это не ошибка, а скорее совет на будущее - одно или дву буквенные алиасы не рекомендуется использовать так как в будущем будет тяжело понять что это значит
в данном случае можно использовать string в качестве алиаса

в принципе тот же совет что и выше про алиасы, лучше называть переменные и аргументы какими то осмысленными словами. через месяц или два становится очень трудно понять что значит буква c

хорошее решение через map
еще мы на втором уроке говорили про clojure.string/replace эта функция здесь хорошо бы подошла
