Sure, but runtime depends on your luck.

#!/usr/bin/env perl use strict; use warnings; use List::Util qw( shuffle reduce ); my @list = qw( f a d e z x c b ); sub in_order { my $state = 1; our( $a, $b ); my $ordered = reduce { if( $state and $b lt $a ) { $state = undef; } + $b } @_; return $state; } my $shuffles = 0; my @ordered = @list; my %memory; until ( in_order( @ordered ) ) { $memory{ join("\0",@ordered) } = 1; while( 1 ) { @ordered = shuffle( @list ); $shuffles++; last unless $memory{ join("\0",@ordered) }; } } print "took $shuffles shuffles to get\n\t", join( "\n\t", @ordered ), +"\n"; exit 0; __END__
