A regular bracket-sequence is a string of characters consisting only of opening and closing brackets, and satisfying the following conditions:

• An empty string is a regular bracket-sequence.
• If A is a regular bracket-sequence, then (A), [A] and {A} are also regular bracket-sequences.
• If A and B are regular bracket-sequences, then AB is also a regular bracket-sequence. For example, the sequences [({})], [](){} and [{}]()[{}] are regular, but the sequences [({{([, []({)} and [{}])([{}] are not.

Ivica has found a string which looks like it could be a regular bracket-sequence. Some of the characters have become smudged and illegible, and could have been any character.

Write a program that calculates how many ways the illegible characters in the string can be replaced by brackets so that the result is a regular bracket-sequence. This number can be very large, so output only its last 5 digits.

Input Specification

The first line contains an even integer ~N~ ~(2 \le N \le 200)~, the length of the string.

The second line contains the string. Illegible characters are represented by the ? character.

Output Specification

Output the number of regular bracket-sequences the string could have read.
