How to find the length of the shortest word in a string with Scala

Answer 1

object ShortestWordLen {

  def shortestWordLength(text: String): Int = {
    // split on whitespace; filter removes empty strings
    val words = text.split("\\s+").filter(_.nonEmpty)

    if (words.isEmpty) 0
    else words.map(_.length).min
  }

  def main(args: Array[String]): Unit = {
    val input = "Find the shortest word length in this string"
    val result = shortestWordLength(input)

    if (result == 0)
      println("No words found.")
    else
      println(s"Length of the shortest word: $result")
  }
}

  
  
  
/*
run:
  
Length of the shortest word: 2
  
*/
