Just print m and verify manually.

For some reason I can't view your solution anymore. "This comment has been hidden" :( (from what I remember, your solution was correct besides that small mistake that you corrected so I don't know why it doesn't pass).

Yes @cdipietro11 I am encountering the same problems. Also, I have verified that the code is mathematically correct. Yet i am getting whole number solutions in test cases when the expected result is -1. Could someone help me out with this?

Thanks for the suggestion! It helped me correct the mistake I was making.
Unfortunately I am still getting integer solutions in some cases where the expected result is -1. As a result I couldn't pass the random tests.
