Key values would not necessarily be unique but you could search the hash for
keys who have values equal to "1":
foreach (keys %week) {
if ($week{$_} == 1) {
print "$_\n";
}
}
You were probably looking for something like $key = $week{$key} but given
that values are not necessarily uniqye that would cause problems in a data
structure of key/value pairs.
Hope this helps.
Kind regards,
