Problem: A **bracket sequence** is a string that is one of the following:    1. An empty string;   2. The concatenation of `(`, A, and `)` in this order, for some bracket sequence A ;   3. The concatenation of A and B in this order, for some non-empty bracket sequences A and B /  Given are N strings S_i. Can a bracket sequence be formed by concatenating all the N strings in some order?
