11.1 练习
- 练习 11.1：当我们对一段文本执行统计单词出现频率的程序时，结果常常是一些诸如冠词和介词之类的没有太多意义的短词汇。请改写该程序，使它忽略长度小于4个字母的单词。
直接从 github 上复制一段 Readme 的内容进行测试，顺便把第二题也完成，思路是，在处理完源文件以后，再读取需要排除的词，将读取到的键值设为 nil 即可将结果从表中移除。

for line in inputFile:lines() do
for word in string.gmatch(line, "%w+") do
if #word >= 4 then
counter[word] = (counter[word] or 0) + 1
end
end
end
for line in exceptionFile:lines() do
for word in string.gmatch(line, "%w+") do
counter[word] = nil
end

Export/import animations to/from sprite sheets, GIF files, or sequence of PNG files (and FLC, FLI, JPG, BMP, PCX, TGA).
Multiple editors support.
Layer groups for organizing your work, and reference layers for rotoscoping.
Pixel-art specific tools like Pixel Perfect freehand mode, Shading ink, Custom Brushes, Outlines, Wide Pixels, etc.
Other special drawing tools like Pressure sensitivity, Symmetry Tool, Stroke and Fill selection, Gradients.
Tiled mode useful to draw patterns and textures.
Transform multiple frames/layers at the same time.
Lua scripting capabilities.
CLI - Command Line Interface to automatize tasks.
Quick Reference / Cheat Sheet keyboard shortcuts (customizable keys and mouse wheel).
