+# There is an array of integers. There are also disjoint sets, and , each containing integers. You like all the integers in set and dislike all the integers in set . Your initial happiness is . For each integer in the array, if , you add to your happiness. If , you add
+
+# to your happiness. Otherwise, your happiness does not change. Output your final happiness at the end.
+
+# 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
