Given a Scanner reference variable named stdin that has been associated with an input source consisting of a sequence of lines, write the code necessary to read in every

line and print them all out on a single line, separated by a space. There should NOT be a trailing space at the end of the line.

Additional Notes: Regarding your code's standard output, CodeLab will check for case errors and will check whitespace $($tabs$,$ spaces, newlines$)$ exactly.
