This should provide you a couple hints:

$ cat #!/usr/bin/perl use strict; use warnings; my @list = (1, 2, 3, 9, 6, 4, 5, 7, 0); while (@list) { my $idx = int rand @list; next if grep { $list[$idx] > $_ } @list; say splice @list, $idx, 1; }

On my machine, this produces:

$ perl 0 1 2 3 4 5 6 7 9

You'll want to make appropriate changes to improve performance, use files, etc.

Update: Hung a lantern on it.


When your only tool is a hammer, all problems look like your thumb.
