Shreyan is appearing for CAT examination and is stuck at a problem to find minimum value needed to be added or subtracted to make a number perfect square.You as his friend and a good programmer agrees to help him find the answer. 

INPUT:

First line will contain no of test cases T (1 < T < 10000)

Next T lines will have integer N (1 < N < 1000000000000)

OUTPUT:

Print YES if the N is a perfect square.

If not then print the minimum value that must be added or subtracted to N to make it perfect square with sign

SAMPLE INPUT
3
25
168
19

SAMPLE OUTPUT
YES
+1
-3

Explanation

25 is prefect square so output is YES

168 is not perfect square but if 1 is added then 169 is perfect square.

19 is not perfect square but if 3 is subtracted it becomes 16 which is a perfect square and if 6 is added it becomes 25 which is perfect square but we choose 3 as its is the minimum value
import math
test = int(raw_input())
while test>0 :
	n = int(raw_input())
	sq = math.sqrt(n)
	f = math.floor(sq)
	c = math.ceil(sq)
	if int(f)**2 == n:
		print("YES");
	else:
		f = int(f)**2
		c = int(c)**2
		c = c - n
		f = n - f
		if c<f:
			print('+'+str(c))
		else:
			print('-'+str(f))
	test-=1
