Your arithmetic is odd. You say
9-4 = 2
and so your resulting list should be (2,4,2). If you want to subtract the
previous result from the next item in your data list each time then this
the job.
HTH,
Rob
use strict;
use warnings;
my @data = (2, 6, 9);
my @delta = @data;
my $prev = 0;
$prev = $_ = $_-$prev for @delta;
print "@delta\n";
**OUTPUT**
2 4 5
Jay's solution is very similar but preferable to mine.
