 Need Help??

L~R's solution has problems:

```\$data_array_ref = [
mykey1 => {firstkey => 'firstvalue', secondkey => 'secondval' },
mykey2 => {ninza => 'turtle', 'Hurricane' => 'Dennis'},
mykey3 => [ ['one', 'two', 'three'] ],
mykey4 => [ [4, 5, 'three'], [6, 7, 'four'], [8, 9, 'five'] ],
];

for ( @\$data_array_ref ) {
print "\$_ =>";
if ( ref \$_ eq 'ARRAY' ) {
print join ", ", @\$_;
}
else {
print join ", ", sort values %\$_;
}
print "\n";
}

__END__
```output
======
mykey1 =>
HASH(0x1abefc0) =>firstvalue, secondval
mykey2 =>
HASH(0x1abf0a4) =>Dennis, turtle
mykey3 =>
ARRAY(0x1ab5148) =>ARRAY(0x1ab50d0)
mykey4 =>
ARRAY(0x1ab52f8) =>ARRAY(0x1ab5190), ARRAY(0x1ab5208), ARRAY(0x1ab5280
+)

My solution:

```\$data_array_ref = [
mykey1 => {firstkey => 'firstvalue', secondkey => 'secondval' },
mykey2 => {ninza => 'turtle', 'Hurricane' => 'Dennis'},
mykey3 => [ ['one', 'two', 'three'] ],
mykey4 => [ [4, 5, 'three'], [6, 7, 'four'], [8, 9, 'five'] ],
];

my \$i = 0;
while (\$i < @\$data_array_ref) {
my \$key = \$data_array_ref->[\$i++];
my \$val = \$data_array_ref->[\$i++];

print "\$key => ";

if (ref(\$val) eq 'HASH') {
print join ', ',
values %\$val;
}
else
{
print join ', ',
map { @\$_ }
@\$val
}

print "\n";
}

__END__
output
======
mykey1 => firstvalue, secondval
mykey2 => turtle, Dennis
mykey3 => one, two, three
mykey4 => 4, 5, three, 6, 7, four, 8, 9, five

It be somewhat easier if your topmost data structure was a hash, not an array.

map { @\$_ } @\$_ flattens a ref to an array of arrays of scalars, as opposed to @\$_ which only flattens a ref to an array of scalars.
