How to find the second largest word in a string with Scala

Answer 1

object SecondLargestWordFinder {
  def main(args: Array[String]): Unit = {
    val str = "Scala lets you write less to do more. As a high-level language"
    
    val secondLargestWord = findSecondLargestWord(str)
    
    println(s"The second largest word is: $secondLargestWord")
  }

  def findSecondLargestWord(str: String): String = {
    val words = str.split("\\s+")
    
    val sortedWords = words.distinct.sortBy(-_.length)
    
    if (sortedWords.length > 1) sortedWords(1) else ""
  }
}
