Complete the code to output $"4$ quarts $=1$ gallon". On the next line, output the value of volQts to three digits after the decimal point, followed by $"$ quarts $=",$ and then the value of volGals to four digits after the decimal point, and lastly "gallons". End with a newline.

Ex: If the input is $32\mathrm{.}000,$ then the output is:

$4$ quarts $=1$ gallon

$32\mathrm{.}000$ quarts $=8\mathrm{.}0000$ gallons

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