// P06 (*) Find out whether a list is a palindrome.
// Example:
// scala> isPalindrome(List(1, 2, 3, 2, 1))
// res0: Boolean = true

object Problem06 {
  def main(args: Array[String]) {
    val values = List(1, 2, 3, 2, 1)
    println(isPalindrome(values))
  }

  // considering the reverse function was written
  // in Problem 05, it's fair to use the builtin one here.
  def isPalindrome[T](values: List[T]) : Boolean = 
    values == values.reverse
}
