It really depends on the data. Are you certain that both lists will be =
in
the same order? Are you certain that all data will exist for each =
person? If
so you can just loop though both lists. That's not very robust, though,
because as soon as you get a value that is one list and not the other,
everything gets out of sync.
I'd probably do something like the following, which stores the is in =
the
array index, as well as the first element:
push my @[EMAIL PROTECTED]
[@[EMAIL PROTECTED]
@[EMAIL PROTECTED]
push @[EMAIL PROTECTED]
(@[EMAIL PROTECTED]
@[EMAIL PROTECTED]
)[1];
$c[$_->[0]] =3D [ @[EMAIL PROTECTED]
] while $_ =3D shift @[EMAIL PROTECTED]
push @[EMAIL PROTECTED]
>[0]]}, $_->[1] while $_ =3D shift @[EMAIL PROTECTED]
