How to remove the middle word from a string in Scala

Answer 1

object RemoveMiddleWordFromString_Scala {

  def main(args: Array[String]): Unit = {
    val str = "scala c c++ java rust"

    val result = removeMiddleWord(str)

    println(result)
  }

  def removeMiddleWord(input: String): String = {
    // Split the string into words
    val words = input.split("\\s+").filter(_.nonEmpty)

    // If fewer than 3 words, nothing to remove
    if (words.length <= 2) return input

    // Calculate the middle index
    val middleIndex = words.length / 2

    // Create a new string without the middle word
    (words.take(middleIndex) ++ words.drop(middleIndex + 1)).mkString(" ")
  }
}
