    I don't see "+ }" in either code example. I suspect that you're cutting and pasting from the screen into your editor, because when formatted code lines wrap, the wrap is indicated with a "+" symbol. You can either remove the unwanted "+" symbols, or use the "download" link, in which case you'll get the code by itself in a web page which you can either right-click and "save as" or cut & paste without the "+" symbols appearing.

    Note: I don't know what your code wrap settings are, but you could always make them wider. (Neither code example wraps with the settings I use.

    Update: I just logged out and looked at the code--McA has two lines that wrap using the default settings, so try the download link. Also, when you're logged out, the plus symbols that indicate wrapping are shown in red, so that'll make the extra "+" symbols easier to find if you just want to delete them in your editor.


    When your only tool is a hammer, all problems look like your thumb.


      I can't believe it. You are speaking about solving relatively complex graph-exploration problems, and you can't even figure out how to remove a so-called "bug" introduced by a clumsy copy-and-paste which just added a + character to the algorithm proposed to you? Come on, that's an easy one. May be you should start learning Perl, rather than asking other people to do your work or your homework for you.
