Answer 1

object SecondSmallestWordLength_Scala {
  def secondSmallestWordLength(string: String): Int = {
    val arr = string.split(" ")

    if (arr.length < 2) {
      return -1
    }

    val lengths = arr.map(_.length).sorted

    lengths(1)
  }

  def main(args: Array[String]): Unit = {
    val str = "c# java c++ python scala"
    
    println(secondSmallestWordLength(str))
  }
}
