Complete the body of the following public static method. You should use nextWordOrSeparator in your solution, because (except for END_OF_INPUT as explained below) "token" here means "word" as used in nextWordOrSeparator.

/**

public static Queue tokens(SimpleReader in) {...}

The END_OF_INPUT token used in the ensures clause is defined as a String constant as follows:

/**

* Token to mark the end of the input. This token cannot come from the input

* stream because it contains whitespace.

*/

public static final String END_OF_INPUT = "### END OF INPUT ###";
