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
t=input()
while t>0:
	try:
		n=input()
		q=int (math.sqrt(n))
		if (q**2)-n==0:
			print "YES"
			continue
		else:
			c=min(n-(q**2),(((q+1)**2)-n))
			if c==n-(q**2):
				c=-1*c
				print c
				continue
			if c>0:
				print '%+d'%(c)
		t-=1
	except(EOFError):
		break
