fun main(args: Array<String>) {
  val sentence = "I am 22 years old because I was born in 1994"
  
  fun getNumbers(sentence: String): List<Int> {
    val numbers = mutableListOf<Int>()
    for (word in sentence.split(" ")) {
      if (word.matches(Regex("\\d+"))) {
        numbers.add(word.toInt())
      }
    }
    return numbers
  }
  
  println(getNumbers(sentence))
}
