Editorial for COCI '10 Contest 5 #1 Gljive

Remember to use this editorial only when stuck, and not to copy-paste code from it. Please be respectful to the problem author and editorialist.
Submitting an official solution before solving the problem yourself is a bannable offence.

Notice that distance between the numbers $X$ $X$ and $100$ $100$ is equal to:

$X-100$ $X - 100$ , if $X$ $X$ is greater than $100$ $100$
$100-X$ $100 - X$ , otherwise

We add numbers one by one starting from the first. If the running sum becomes greater than $100$ $100$ , our solution is either the previous sum we had, or the current sum. We choose the sum closer to $100$ $100$ .

If the sum of all the numbers is not greater than $100$ $100$ , we output this sum.
