Write a program to find the maximum volume of given geometric \textbf{3}-dimensional figures. Here, there are \textbf{3} types of figures: cone, cylinder and sphere. \includegraphics{https://static.e-olymp.com/content/a5/a5d51a15d6044f985bbb860b50b1b0f27a4f2859.jpg} The volume (\textbf{V}) of each figure can be calculated by the following formulas. \includegraphics{https://static.e-olymp.com/content/49/49270e28ebc371c9e6e548fe5edf6353526f0ecb.jpg} Cone: \textbf{V = (1/3)r^2h} \includegraphics{https://static.e-olymp.com/content/49/49270e28ebc371c9e6e548fe5edf6353526f0ecb.jpg} Cylinder: \textbf{V = r^2h} \includegraphics{https://static.e-olymp.com/content/49/49270e28ebc371c9e6e548fe5edf6353526f0ecb.jpg} Sphere: \textbf{V = (4/3)r^3} \includegraphics{https://static.e-olymp.com/content/49/49270e28ebc371c9e6e548fe5edf6353526f0ecb.jpg} Use the value \textbf{ = 3.14159} in your calculation. \InputFile The first line of the input contains a positive integer \textbf{n} (\textbf{1} ≤ \textbf{n} ≤ \textbf{100}) which is the number of figures. The \textbf{n} following lines contain the description of each figure. In case of a cone, the line begins with letter \textbf{C} and followed by \textbf{2} values: \textbf{r }and \textbf{h} respectively. If it is a cylinder, the line begins with letter \textbf{L} and followed by \textbf{2} values: \textbf{r} and \textbf{h} respectively. If it is a sphere, the line begins with letter \textbf{S} and followed by only one value which is \textbf{r}. \OutputFile Print out the max volume among the input figures with \textbf{3} decimal places.
