  def replaceMultipleSpaces(str: String): String = {
    // Use a regular expression to replace multiple spaces with a single space
    val result = str.replaceAll("\\s+", " ")

    // Trim leading and trailing spaces
    result.trim
  }

  def main(args: Array[String]): Unit = {
    val str: String = "   This   is    a   string   with   multiple    spaces   "
    val outputString: String = replaceMultipleSpaces(str)

    println(s""""$outputString"""")
