2 Kotlin

fun printerError(s: String): String {
    val total: Int = s.length
    val part: Int = total - "[a-m]".toRegex().findAll(s).count()
    return part.toString() + "/" + total.toString()
}

fun printerError(s: String) = "${s.count { it !in 'a'..'m' }}/${s.length}"

fun printerError(s: String): String {
  val wrong = s.count { it.toInt() > 'm'.toInt() }
  return "$wrong/${s.length}"
}

fun printerError(s: String): String {
    return "${s.count{it > 'm'}}/${s.length}"
}

3 R

}

printerError <- function(s) {
  sprintf("%d/%d", nchar(gsub("[a-m]", "", s)), nchar(s))
}

printerError <- function(s) {
  ns <- nchar(s)
  errors <- nchar(gsub("[a-m]", "", s))
