this shouldn't pass the test. this kindda glitch could be avoided if more test were added.

Hello, bainhome. I agree that more test cases should be included in the Test Suite (a minimum of four cases). It would be instructive if you could suggest specific test cases which this submission wouldn't pass. —DIV

One such test case would be x=1, p=1, c=0.9; the correct solution for this should be y=1.
