    效果很好，尤其是 EXE 的 Base64，但是目前只适用于 A，若要扩展到其他字符，如何区分不同的层？

如果不考虑复杂度的话，该算法还可优化，例如：
AAAAAAAABBBBBBBBCDEBBBBBBBBCCCCAAAAAAAAAAAA

用顶楼算法得到的结果是：
#  BBBBBBBB  CDE  BBBBBBBB  CCCC  #-

进一步压缩得到的结果是（规则参考附文）：
#  >B#  CDE  #  >C-  <#-
规则是在重复字符发生变化的节点前声明此后的重复字符，如多个重复字符串比邻，则仅需声明一次：
>B 此后的所有 @ - # $ _ } { ] [ 均表示特定个数的 B
>C 同上，表示特定个数的 C
<  同上，表示特定个数的 A(默认)
接下来可以再考虑如何处理重复的词
