**Problem Description**

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
