  $ perl -wE '@h{1..shift}=(); say scalar %h;' 16384
  12812/32768
  $ perl -wE '@h{1..shift}=(); say scalar %h;' 32768

  • 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.
