# No Idea in python HackerRank Solution 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, don’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.

```3 2
1 5 3
3 1
5 7
```

```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.

```# No Idea in python - Hacker Rank Solution START
io = input().split()
m = int(io)
n = int(io)
storage = list()
count = 0
storage = list(map(int, input().strip().split()))
A = set(map(int, input().strip().split()))
B = set(map(int, input().strip().split()))
for i in storage:
if i in A:
count = count+1
if i in B:
count = count-1
print(count)
