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 C# (judge verdict: Accepted)

using System;

class AOJ{
  static void Main(string[] args)
  {
    int[] a = new int[4];
    int[] b = new int[4];
    int hit, blow;

    string[] s1, s2;
    string str;

    while ((str = Console.ReadLine()) != null){

      s1 = str.Split(' ');
      s2 = Console.ReadLine().Split(' ');

      for (int i = 0; i < 4; i++){
        a[i] = int.Parse(s1[i]);
        b[i] = int.Parse(s2[i]);
      }

      hit = 0;
      blow = 0;

      for (int i = 0; i < 4; i++){
        if (a[i] == b[i])
          hit++;
        for (int j = 0; j < 4; j++){
          if (a[i] == b[j])
            blow++;
        }
      }

      blow -= hit;

      Console.WriteLine("{0} {1}", hit, blow);
    }
  }
}
