1.如果淨係放嗰個txt file佢唔識encrypt 後output 個encrypt後嘅document .即係我如果delete咗wiki_e.txt佢唔識自己再output。需要人手開一個新txt document 

詳情可以睇 Problem1.mp4

2. 1.如果篇文有兩個相同(無論係相同或者多過)字數嘅Alphabet 出現 呢個時候個program就會encrypt錯。例如將「people 」呢隻字打到200字 「P」同「E」嘅數量係一樣 
所以encrypt完之後變出嚟嘅亂碼 再decrypt唔會變返「People」所以要搵解決方法做到點樣先可以知道decrypt gen出嚟嘅key(k)係準確。

詳情可以睇Problem2 (Alphabet E is the same with P).mp4 Problem 2( Alphabet P is more than E and the guess of Key is error).mp4

阿sir指定話要將呢個problem寫入report睇下點樣solve同埋點解會出現呢個情況. Thanks very much


3.個Guildline要求無論係Uppercase定LowerCase都要直接將佢變成Uppercase但係只有文字轉Uppercase標點符號同埋spaces唔會改變。

即係gen出嚟嘅亂碼會係全大階。 （咁係唔係即係delete咗Lowercase段code就得？） 

4.要加多個flow chart喺report入面係整合曬成個program. 

Thanks a lot for helping me.!!!!!!
