The reciprocal of width$\_$input is $1/$ width$\_$input. 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 $0\mathrm{.}610,$ then the output is:

The reciprocal of width $=1/0\mathrm{.}610=1\mathrm{.}639$
