## 解題思路
題目給的兩個 txt 檔案如下左，~~然後給的 python 檔案也沒什麼用~~，只好看著他給的 study-guide 通靈

在通靈中覺得很奇怪，flag 是亂碼很正常，但 study-guide 也是亂碼，真的是在通靈ㄟ，所以我把他丟上去做平率分析...... ，看起來解析得還不錯 OUO

解析的第一行長這樣
```
urchicine malfeasor greenheart baptistry litorinoid vindicatory stockrooms flindersia disagreeability frohlich disamenity outsparspying preinclination melanizing preobedient chloralformamide nonelectrolytic ascertainable thoracoplasties pinnaclet paperweights incarnation nonpuerility unprefined brasslike transpositive glycerol idolatrizer hyperoartia perimedullary rendition monstricide extraspectral monumentally cholehematin overrealism dinnerless carpellum barrulee extrovertedness necessar evincing perspectivism plasmolyzability noctilucal intertarsal essoinment paratypic borstall misadressing antitabetic computerizable dehisces redodoing postnasal minatorially cyllenian isuridae saccharine conversaziones unwearisome twinflower blessing unescalloped ancylostomiasis
```

將 flag.txt 丟上去解析看看，喔吼出來啦
