Hi, possibly this post might be off topic but anyways, I have been browsing around your blog and it appears very neat. It is obvious that you know the topic and you seem passionate about it. We are constructing a fresh weblog plus I’m attempting to make it look good, as well as offer quality message. I have discovered much visiting your internet site and also I anticipate more quality information and will be coming back soon. Many thanks.

// If this is a “non-white-space characters” minimum contest, you can
// return instead:
return !(total % 10);

// or simply remove your ()’s… 18 vs 20 :-)

you can replace:

// If the total mod 10 equals 0, the number is valid
if (total % 10 == 0) {
return true;
} else {
return false;
}

with

// If the total mod 10 equals 0, the number is valid
return (total % 10 == 0);
