[Tutor] Tutor Digest, Vol 64, Issue 80

[Benjamin Serrato]

Wayne already explained slicing but I would like to point out the
digit after the second colon changes the default step of the slice.
Usually it defaults to 1, here because no values were given it takes
the entire string and steps backward.  You could set it to 2.

First digit, beginning of slice, second digit end of slice, third
digit is the jump to the next item in the sequence.

HTH,
Ben S.
