Problem:
Hit and Blow

Let's play Hit and Blow game. A imagines four numbers and B guesses the numbers. After B picks out four numbers, A answers:

The number of numbers which have the same place with numbers A imagined (Hit)

The number of numbers included (but different place) in the numbers A imagined (Blow)

For example, if A imagined numbers:

9 1 8 2

and B chose:

4 1 5 9

A should say 1 Hit and 1 Blow.

Write a program which reads four numbers A imagined and four numbers B chose and prints the number of Hit and Blow respectively. You may assume that the four numbers are all different and within from 0 to 9.

Input

The input consists of multiple datasets. Each dataset set consists of:

a1 a2 a3 a4
b1 b2 b3 b4

, where ai (0 ≤ ai ≤ 9) is i-th number A imagined and bi (0 ≤ bi ≤ 9) is i-th number B chose.

The input ends with EOF. The number of datasets is less than or equal to 50.

Output

For each dataset, print the number of Hit and Blow in a line. These two numbers should be separated by a space.

Sample Input

9 1 8 2
4 1 5 9
4 6 8 2
4 6 3 2

Output for the Sample Input

1 1
3 0

Solution in Scala (judge verdict: Accepted)

object Main {
  def main(args: Array[String]) = {
    val s = scala.collection.mutable.Queue[String]()

    for (x <- io.Source.stdin.getLines()) {
      s += x
      if (s.size == 2) {
        val a = s.dequeue().split(' ').map(n => n.toInt)
        val b = s.dequeue().split(' ').map(n => n.toInt)
        val (hit, blow) = hitAndBlow(a, b)
        println(hit + " " + blow)

      }
    }
  }

  def hitAndBlow(a: Seq[Int], b: Seq[Int]): Tuple2[Int, Int] = {
    var hit = 0
    for (i <- 0 until 4) {
      if (a(i) == b(i)) {
        hit += 1
      }
    }

    val blow = a.intersect(b).size - hit

    (hit, blow)
  }
}
