~~~求一复杂的正则表达式~~~~~~求一复杂的正则表达式~~~~~~求一复杂的正则表达式~~~
一个朋友的一个题目，想了半天没想出来。请各位前辈帮帮忙。题目如下：
在给你的长序列文本中搜寻下面模式：
NNNNNNNNN1N2N3N4N5N6 NNNNNNNN N6N5N4N3N2N1N7N8N9N10N11 N12N13 NNNNNNNNNNNN13N12N11N10N9N8N7NNNNNNN
说明 :
1. N，NI (I=1,2,3,……13)代表A,G,C,T的任意一种.A与 T相互补，G与C相互补；
2. 连续的 N表示A、G、C、T的任意组合且长度不限制;
3. N1与N1 是互补字母，比如 N1 是 G， N1则是C；其他类推。
（上面一大串N中的数字是脚标）
长序列文本内容如下（很长，我截取了一段）：
