Re: How can I add all the numbers in an array with out doing a foreach loop?

He's a rather ridiculous solution which avoids using the addition operator. It only works for positive integers.

my @quans = (2, 5, 8, 12, 15, 88);
my $total = scalar(map {1 .. $_} @quans);
print "$total.\n";

This is very ineffective way of counting the sum. Try adding 100000000 into the array. What your solution does is it creates ranges `1 .. $_` for each number in the list, and then counts how many members the whole sequence has.
