Notes: For some of the input on uDebug, an ε (Epsilon) of 1e-6 to 1e-10 must be used to avoid precision loss​. If an ε of less then 1e-6 is used the answer is 5 else it's 6. The judge's input most probably does not contain a similar test case.

Print a blank line between test cases - not after each test case. (So, there should not be a blank line printed after the last test case.) Printing a blank line after each test case will result in a verdict of wrong answer on UVa Online Judge.
