[PC_10] what are you looking at?

一进去就看到上关画出来那头牛的真面目了，满帅的哈哈~~

然后一个问题： len(a[30])=? 源文件什么提示都没有~

点一下牛图片有个txt文件： a = [1, 11, 21, 1211, 111221, 是道数列题。

我现在当然知道是怎么做，可当时和 RhythmBox 刚开始做这题的时候为了找 a 的规律冥思苦想了好几天呢~

后来公务员考试期间拿这道题考 glitter 和 tomcat ，得知这个竟是 google 的一道面试题，~>.<~ 看来牟希望去 google 了么~~~

呵呵，还有，当时寝室都在准备考研，为了不把精力浪费在 PythonChallenge 上，寝室里一度发誓不写python的，不过最后到底抵挡不住 python challenge 的诱惑，于是我用 c 写了程序过了这关~

那好吧，现在把 python 的代码补上~~ ：）

[code]

a = ['1']
ss = ''

for k in range( 31 ):
     s = a[-1] + '$'
     c = s[0]
     count = 0
     for j in range( len(s) ):
         if s[j] == c :
             count += 1
         else :
             ss = ss + str( count ) + c
             c = s[j]
             count = 1
     a.append( ss )
     ss = ''

print len(a[30])

结果：5808
