my %data = (
k1 => 'a',
k2 => ['b', 'c'],
k3 => ['d', 'e', 'f']
k4 => 'a'
);
I want to get all the possible combinations:
k1 => a
k2 => b
k3 => d
k4 => a
k1 => a
k2 => c
k3 => d
k4 => a
k1 => a
k2 => b
k3 => e
k4 => a
k1 => a
k2 => c
k3 => e
k4 => a
k1 => a
k2 => b
k3 => f
k4 => a
k1 => a
k2 => c
k3 => f
k4 => a
On a larger list ( 20 items) what's a good way to do this? My head is
just kind of stuck on this...
