Problem:
 Score : 600 points    Problem Statement A bracket sequence is a string that is one of the following:   An empty string;  The concatenation of ( , A , and ) in this order, for some bracket sequence A ;  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?      Constraints  1 \leq N \leq 10^6  The total length of the strings S_i is at most 10^6 .  S_i is a non-empty string consisting of ( and ) .         Input Input is given from Standard Input in the following format:  N  S_1  :  S_N       Output If a bracket sequence can be formed by concatenating all the N strings in some order, print Yes ; otherwise, print No .
