Find the focal length of the spherical mirror with the given radius-of-curvature R.
The first line of the input contains a positive integer T, denoting the number of test cases. For each test case , there will be two lines. First line contains type of mirror, and second line contain R (Radius of curvature).
Output: For each testcase, print the floor of the focal length.
