print "$_", join(',',sort keys %$h),"\n";
It's giving me an error below:
Use of uninitialized value in string at missing_months.pl line 36.
1,10,11,12
this print statement is present in a for loop as below:
foreach my $num ( sort keys %hash )
{
my $h = $hash{$num};
print "$_", join(',',sort keys %$h),"\n";
}
