Re: confused with summing certain elements from an array

A hash is not sorted, by definition. You can sort the keys when you print it, though.

my %counts;
for (0 ... $#out){
    $counts{$out[$_]} += $out1[$_];
}

should build the hash.

Update: the Perl 6 solution is much prettier, btw:

for @out Z @out1 -> $char, $count {
     %hash{$char} += $count;
}

Looks ambiguous to me. "For array iterator array1 points to scalar var and count var, increment hash at var by count" if I had never seen perl 6 code before.	[reply]
