I like stooge sort more. It can be much more efficient: I used functional-programming techniques which means it can be trivially parallelised over many CPUs.

sub stoogesort { my (@lst) = @_; if ($lst[-1] < $lst[0]) { # swap @lst[0, -1] = @lst[-1, 0]; } return @lst if (@lst < 3); # thirds my $zero = 0; my $one = int(@lst / 3); my $two = int($#lst * 2 / 3); my $three = $#lst; for my $range ( [ $zero .. $two ], [ $one .. $three ], [ $zero .. $two ] ) { @lst[ @$range ] = stoogesort( @lst[ @$range ] ); } return @lst; } my @list = (1, 2, 3, 9, 6, 4, 5, 7, 0); print join(" ", stoogesort(@list)), "\n";
