Post #2 of 3
The @new array is left unchanged at
5, 2, 4, 8;
How? I don't have my books handy, but i think it goes something like this.
First the call is made to Sort::cure, where
$a and $b are package global variables. These should be qualified with the package name of the caller, since the sort routine is not in the same package as the caller
Since $a and $b are out of scope, the subroutine returns '0' for each call.
Then sort compares the values returned from
Sort::cure, and since they are all '0', the order remains unchanged.
This populates the @new array with the unchanged list of values.
