Complete the code to output $"7$ days $=1$ week". On the next line, output the value of lengthDays to three digits after the decimal

point, followed by $"$ days $=",$ and then the value of lengthWeeks to four digits after the decimal point, and lastly $"$ weeks". End with

a newline.

Ex: If the input is $21\mathrm{.}000,$ then the output is:

$7$ days $=1$ week

$21\mathrm{.}000$ days $=3\mathrm{.}0000$ weeks

Note: System.out.printf$()$ can be used with $"\%.$Xf$"$ to output a double to $x$ digits after the decimal point.
