Problem Description

Now I define the relations between two integers as following:
1. Let NA be the number of factors of A;
2. Let NB be the number of factors of B;
3. A>B if and only if NA > NB;
4. A=B if and only if NA = NB;
5. A<B if and only if NA < NB;

For example, the factors of 12 are 1,2,3,4,6,12, so the number of factors of 12 is 6; and the factors of 21 are 1,3,7,21, so the number of factors of 21 is 4. So we can say 12>21.

Ha-ha! Maybe everything is possible!

Input

Input contains multiple cases, Each case consists of a pair of integers A and B(0<A,B<100000000), separated by a space, two negative numbers will end the input.

Output

For each case you should output the relation of A and B.
Output format is as sample output.

Sample Input
3 4 
7 5
12 21
-1 -1
Sample Output
3<4 
7=5
12>21
