[Basic] Maximum and Minimum Of Array Elements

Given an array, find maximum and minimum elements from the array.

Input:

The first line of input contains an integer T denoting the number of test cases. The description of T test cases follows. The first line of each test case contains a single integer N denoting the size of array. The second line contains N space-separated integers A1, A2, …, AN denoting the elements of the array.

Output:

Print the maximum and minimum element in a single line with space in between.

Constraints:

1 ≤ T ≤ 30

1 ≤ N ≤ 100

0 ≤A[i]<100

Example:

Input: 2
4
5 4 2 1
1
8

Output:
5 1
8 8

def max_min_array(arr):
    return ' '.join([str(max(arr)), str(min(arr))])

t = int(input())
for i in range(t):
    n = int(input())
    arr = list(map(int, input().split()))
    print(max_min_array(arr))
