NoteIn the first example, the product of the whole array ($$$20$$$) isn't a perfect square.In the second example, all subsequences have a perfect square product.

The first line contains an integer $$$t$$$ ($$$1 \le t \le 100$$$) — the number of test cases. The description of the test cases follows. The first line of each test case contains an integer $$$n$$$ ($$$1 \le n \le 100$$$) — the length of the array $$$a$$$. The second line of each test case contains $$$n$$$ integers $$...

If there's a subsequence of $$$a$$$ whose product isn't a perfect square, print "YES". Otherwise, print "NO".
