Read a Long Value

Read a large whole number from standard input using sc.nextLong() and print its value multiplied by two. For example, if the input is 1000000000, print the output shown in Expected Output.

Use System.out.println with concatenation.

Expected Output:

Doubled: 2000000000↵

= newline. The output ends with a newline — print one after the last line.
