Provide tags and a correct Python 3 solution for this coding contest problem. This is the easier version of the problem. In this version, 1 ≤ n ≤ 10^5 and 0 ≤ a_i ≤ 1. You can hack this problem only if you solve and lock both problems. Christmas is coming, and our protagonist, Bob, is preparing a spectacular present ...
