You are given a sequence of left and right parentheses of length n. Design a data structure which supports operations "toggle the parenthesis at position ?" (in time O(log n)) and “report whether the sequence is proper” (in O(1)). (A sequence of parentheses is proper if we never close a parenthesis that wasn't opened previously, as we read the sequence from left to right.)
