The reciprocal of input$\_$volume is $1/$ input$\_$volume. The following program intends to read a floating$-$point value from input, compute the reciprocal of the value, and output the reciprocal, but the code contains an error. Find and fix the error.

Ex$.$ If the input is $0\mathrm{.}310,$ then the output is:

The reciprocal of volume $=\frac{1}{0\mathrm{.}310}=3\mathrm{.}226$
