Complete the code to output $"1000$ meters $=1$ kilometer". On the next line, output the value of lengthMeters to three digits after the decimal point, followed by $"$ meters $=",$ and then the value of length $Km$ to three digits after the decimal point, and lastly "kilometers". End with a newline.

Ex: If the input is $5000\mathrm{.}000,$ then the output is:

$1000$ meters $=1$ kilometer

$5000\mathrm{.}000$ meters $=5\mathrm{.}000$ kilometers

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