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=int(input());
for i in range(0,t):
	n=int(input());
	s="";
	k=int(math.sqrt(n));
	d1=n-(k*k);
	d2=((k+1)*(k+1))-n;
	if d1<d2 and d1!=0:
		s="-"+str(d1);
		print s;
	elif d2<d1:
		s="+"+str(d2);
		print s;
	else:
		print("YES");
