[Easy] Merge Two Sorted Arrays

You have to merge the two sorted arrays into one sorted array (in non-increasing order)

Input:

First line contains an integer T, denoting the number of test cases. First line of each test case contains two space separated integers X and Y, denoting the size of the two sorted arrays. Second line of each test case contains X space separated integers, denoting the first sorted array P. Third line of each test case contains Y space separated integers, denoting the second array Q.

Output:

For each test case, print (X + Y) space separated integer representing the merged array.

Constraints:

1 <= T <= 100
1 <= X, Y <= 5*104
0 <= Pi, Qi <= 109

Example:

INPUT:

1
4 5
7 5 3 1
9 8 6 2 0

OUTPUT:

9 8 7 6 5 3 2 1 0

def merge_array(arr1, arr2):
    return ' '.join(map(str, sorted(arr1+arr2,reverse=True)))

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