Conversion to Perl

Conversion

Not a difficult conversion - but a chance to throw in a few ways Perl makes life easy.

• To get the sub permission which is a random location in the g x g x g grid we can use:

  • assigning multiple variables in list form ($a,$b,$c) = (?,?,?)
  • where the list on the right hand side is generated with a map function

• We use ternarys to generate the message if you miss the sub.

  • We use join to stitch the pieces of the string together.
  • If we have a ternary where we don't want to return anything we return an empty list rather than an empty string - if you return the latter you still get the padding spaces.
