create a $.$sed file for linux WITHOUT USING AWK that

$$ has no more than one space between tokens.

$$ has no trailing whitespace after a line.

$$ Binary operators should always surrounded by a single space on either side $($including assignment

and Boolean$).$ Only the following operators must be accounted for: $+,-,*,/,=,==,<=,>=,<,>.$

$$ Conditions should not have whitespace immediately inside of the parentheses.

$$ The program should not modify spaces which are leading, expanded tabs$.$

$$ Comments should be left alone. You may assume comments $($single$-$ and multi$-$line$)$ will not appear

on lines with source code.

Hint: The above need not be performed in a single pass.
