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.
