scala-在奇数位置匹配控制字符

def matchControlCharacters(str: String): Unit = {
  val controlCharacters = List('\n', '\t', '\r', '\f', '\b')
  
  str.zipWithIndex.foreach { case (char, index) =>
    if (index % 2 != 0 && controlCharacters.contains(char)) {
      println(s"Found control character '$char' at odd position $index")
    }
  }
}

val inputString = "Hello\nWorld\tScala\rProgramming"
matchControlCharacters(inputString)
