Note: Since  and  are sets, they have no repeated elements. However, the array might contain duplicate elements.

Constraints

Input Format

The first line contains integers  and  separated by a space.
The second line contains  integers, the elements of the array.
The third and fourth lines contain  integers,  and , respectively.

Output Format

Output a single integer, your total happiness.

Sample Input

3 2
1 5 3
3 1
5 7

Sample Output

1

Explanation

You gain  unit of happiness for elements  and  in set . You lose  unit for  in set . The element  in set  does not exist in the array so it is not included in the calculation.

Hence, the total happiness is .
