I'm not really sure what you're asking, but I think that it is probably
answered by the docs:



http://ruby-doc.org/core/classes/String.html#M000771

str[range] => new str or nil

<http://ruby-doc.org/core/classes/String.src/M000771.html>If given a range,
a substring containing characters at offsets given by the range is returned.
In all three cases, if an offset is negative, it is counted from the end of
*str*.
