Showing error even if the solution is correct. Array Q 22.

I am getting error even though the solution is correct. Code is provided below.

n = int(input()) # no of array
def sort_array(n):
    for i in range(0, n):
        a = int(input())
        a_list = list(map(int, input().split()))
        a_list.sort()
        print(*a_list,end=' ')
sort_array(n)

Input:

3
2
98 12
6
1 2 3 8 5 9
1
11

Output:

12 98 1 2 3 5 8 9 11

I am getting correct output even for test cases. Need to know what is the problem.
