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)

import scala.io.StdIn._

object Main {
  def cardGame(gameNum: Int): List[Int] = {
    def loop(n: Int, p1: Int = 0, p2: Int = 0): List[Int] = {
      if (n > 0) {
        val cards = readLine().split(" ")
        val sortedCards = cards.sorted

        if (cards(0) == cards(1)) loop(n - 1, p1 + 1, p2 + 1)
        else if (cards(0) == sortedCards(0)) loop(n - 1, p1 + 0, p2 + 3)
        else loop(n - 1, p1 + 3, p2 + 0)
      } else List(p1, p2)
    }

    loop(gameNum)
  }

  def main(args: Array[String]): Unit = {
    val gameNum = readInt()
    println(cardGame(gameNum).mkString(" "))
  }
