2017年蓝桥杯省赛A组c++第7题(正则问题)

/*
描述：正则问题

考虑一种简单的正则表达式：
只由 x ( ) | 组成的正则表达式。
小明想求出这个正则表达式能接受的最长字符串的长度。  

例如 ((xx|xxx)x|(x|xx))xx 能接受的最长字符串是： xxxxxx，长度是6。

输入
----
一个由x()|组成的正则表达式。输入长度不超过100，保证合法。  

输出
----
这个正则表达式能接受的最长字符串的长度。  

例如，
输入：
((xx|xxx)x|(x|xx))xx  

程序应该输出：
6

很难的一题，思考了很久，主要还是对于深度优先算法理解不够。这道题是误打误撞做出来的，并没有完全理解。不过看过某大佬画的一张图，感觉有助于理解：
