RE: populating an array with unique integers.

[Wagner-David]

        Use a hash vs array, use the number as a hash key.  If key exists,
then get the next number until you have the number of unique numbers
desired.

        next if ( exists $Unique{$RandomNumber} );
        $Unique{$RandomNumber} = 1;


        for printing:
        foreach my $MyKey (sort keys %RandomNumber ) {
         # print goes here
         }

Wags ;)

Subject: populating an array with unique integers.


I want to create an array, and populate it with random numbers, they should
be unique and sorted (I can sort at the output).  I'm stuck at the unique
part:

generate a random number;
check if the number exists in the array,
     if it exists generate a new one,
     check again until a unique number is found.

once unique add too next place in array.

I think the perldocs are confusing me.

Thanks.

Scott.
