It is a bad idea to use "$a" and "$b" as variable names, especially in a program that does sorting.

Refer to the FAQ "How do I sort an array by (anything)?" for an alternate method. (Your approach is simpler and for small data sets it probably does not matter which you use.)

Title:
Use:  <p> text here (a paragraph) </p>

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • 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.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
