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
from math import *
c = int(raw_input())
for i in range(c):
	i1 = int(raw_input())
	sr = int(sqrt(i1))
	srs = sr ** 2
	if srs == i1:
		print "YES"
	else:
		m = abs(i1 - srs)
		M = abs((sr+1)**2 - i1)
		#print m,M
		if m < M:
			print -m
		else:
			print "+"+str(M)
