Problem:
Card Game

Taro and Hanako are playing card games. They have n cards each, and they compete n turns. At each turn Taro and Hanako respectively puts out a card.
The name of the animal consisting of alphabetical letters is written on each card, and the bigger one in lexicographical order becomes the winner of that turn. The winner obtains 3 points. In the case of a draw, they obtain 1 point each.

Write a program which reads a sequence of cards Taro and Hanako have and reports the final scores of the game.

Input

In the first line, the number of cards n is given. In the following n lines, the cards for n turns are given respectively. For each line, the first string represents the Taro's card and the second one represents Hanako's card.

Constraints

n ≤ 1000

The length of the string ≤ 100

Output

Print the final scores of Taro and Hanako respectively. Put a single space character between them.

Sample Input

3
cat dog
fish fish
lion tiger

Sample Output

1 7

Solution in Scala (judge verdict: Accepted)

object Main extends App {
  val sc = new java.util.Scanner(Console.in)

  def nextInt() = Integer.parseInt(sc.next)
  def next() = sc.next

  def game(n:Int, taro:Int, hanako:Int): Tuple2[Int, Int] = {
    if (n == 0)
      (taro, hanako)
    else {
      val cmp = next compare next
      if (cmp > 0)
        game(n-1, taro+3, hanako)
      else if (cmp < 0)
        game(n-1, taro, hanako+3)
      else
        game(n-1, taro+1, hanako+1)
    }
  }

  val (taro, hanako) = game(nextInt, 0, 0)
  println(s"$taro $hanako")
}
