The same old story :) 
perl -e 'print$}+=$.=$}-$.||1,$/for+e..x'

ruby -e 'x=-1;20.times{p$.+=x=$.-x}'

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
