hihocoder-1284 chances are slim (water problem)

Slim chance time limit: 5000ms single point time: 1000ms memory limit: 256MB description

Small hi recently in pursuit of a math girl little Z. Small z is actually want to reject him, but can not find good rhetoric, so put forward the request: for a given two positive integers n and m, small hi randomly selected an n ' approximate n ', small z randomly selected a m's approximate m ', if n ' and M ' equal, she promised small hi.

Small z let small hi to write this random program, then she review had no problem, you can draw the lottery. But small hi wrote, but more and more feel the opportunity is slim. So the question is, what is the odds that little hi can catch a little z?

Input

Each input file contains only a single set of test data.

The first behavior of each set of test data is two positive integers n and M, meaning as described earlier.

For 40% of data, meet 1<=n,m<=106

For 100% of data, meet 1<=n,m<=1012

Output

For each set of test data, the output of two coprime positive integers A and B (with a per B indicates the chance that small hi can catch small z).

Sample input

Sample output
