WebClearly, every parentheses sequence has a unique closure number. We can try to enumerate them individually. Algorithm. For each closure number c, we know the starting and ending brackets must be at index 0 and 2*c + 1. Then, the 2*c elements between must be a valid sequence, plus the rest of the elements must be a valid sequence.
