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).
