如何在Scala中获取字符串的最后一个元音及其后面的任何单词？

import scala.util.matching.Regex

def getLastVowelAndFollowingWords(str: String): Option[String] = {
  val pattern: Regex = ".*([aeiou])(\\w*)$".r
  str match {
    case pattern(vowel, words) => Some(words)
    case _ => None
  }
}

val inputString = "Hello world"
val result = getLastVowelAndFollowingWords(inputString)
result match {
  case Some(words) => println(s"The last vowel and following words in '$inputString' are: $words")
  case None => println(s"No vowel found in '$inputString'")
}
