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

for t in range(0, int(raw_input())):
	n = (int(raw_input()))
	flag = 0
	root = math.sqrt(n)
	if root == math.floor(root):
		print 'YES'
		continue
	upper = int(((math.ceil(root))**2) - n)
	lower = int(n - ((math.floor(root))**2))
	
	if upper < lower:
		print '+'+str(upper)
	else:
		print '-'+str(lower)
