package solution
fun calculateYears(years: Int): Array<Int> {
    val catYears = if(years<3) 6+9*years else 16+4*years
    val dogYears = if(years<3) 6+9*years else 14+5*years
    return arrayOf(years, catYears, dogYears)
}

package solution
fun calculateYears(years: Int): Array<Int> =
    when (years) {
        1 -> arrayOf(1, 15 , 15)
        2 -> arrayOf(years, 24 , 24)
        else -> arrayOf(years, 24 + 4 * (years - 2), 24 + 5 * (years - 2))
    }

package solution
fun calculateYears(years: Int): Array<Int> {
  return arrayOf(years,
      if(years<2) 15 else 4*years+16,
      if(years<2) 15 else 5*years+14)
