[Easy] Sum of Middle Elements of two sorted arrays

Given 2 sorted arrays A and B of size N each. Print sum of middle elements of the array obtained after merging the given arrays.

Input:
The first line contains ‘T’ denoting the number of testcases. Then follows description of testcases. Each case begins with a single positive integer N denoting the size of array.
The second line contains the N space separated positive integers denoting the elements of array A.
The third line contains N space separated positive integers denoting the elements of array B.

Output:

For each testcase, print the sum of middle elements of two sorted arrays. The number of the elements in the merged array are even so there will be 2 numbers in the center n/2 and n/2 +1. You have to print their sum.

Constraints:
1<=T<=50
1<=N<=1000
1<=A[i]<=100000
1<=B[i]<=100000

Example:
Input :
1
5
1 2 4 6 10
4 5 6 9 12

Output :
11

def sum_of_middle(arr1, arr2):
    arr3 = sorted(arr1 + arr2)
    result = arr3[len(arr3)//2-1] + arr3[len(arr3)//2]
    return result

t = int(input())
for i in range(t):
    n = input()
    arr1 = list(map(int, input().split()))
    arr2 = list(map(int, input().split()))
    print(sum_of_middle(arr1,arr2))
