Hello Programmers, In this post, you will know how to solve the** No Idea in python HackerRank Solution**. This problem is a part of the **HackerRank Python Programming** Series.

One more thing to add, donâ€™t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.

## No Idea in python HackerRank Solution

### problem

There is an array of n integers. There are also 2 disjoint sets, A and B, each containing m integers. You like all the integers in set A and dislike all the integers in set B. Your initial happiness is 0. For each i integer in the array, if i (- A , you add 1 to your happiness. If i (- B, you add -1 to your happiness. Otherwise, your happiness does not change. Output your final happiness at the end.

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

#### Constraints :

- 1 <= n <= 10^5
- 1 <= m <= 10^5
- 1 <= any integer in the input <= 10^9

#### Input Format :

The first line contains integers n and m separated by a space.

The second line contains n integers, the elements of the array.

The third and fourth lines contain m integers, A and B, respectively.

#### Output Format :

Output a single integer, your total happiness.

#### Sample Input :

321533157

#### Sample Output :

1

#### Explanation :

You gain 1 unit of happiness for elements 3 and 1 in set A. You lose 1 unit for 5 in set B. The element 7 in set B does not exist in the array so it is not included in the calculation.

Hence, the total happiness is 2 – 1 = 1.
