Later versions of perl moved beyond fundamentals types of scalar, array, and hash and introduced a reference type.
Write down the Perl subroutine, referenceTypeExample, to show understanding of Perl's reference type:
Create the integer variable "theInt" which is set to 42.
Create the alias for theInt
Using alias, increase value of integer variable by one
Print the value of theInt (it must be 43)
Print the value of the alias
Print value of theInt using alias
