zerojudge 進不去題目

今天寫題目寫到一半，要進去重新看題目時，發現進不去，並跳出許多錯誤訊息，如下:

*可惜沒摸過，看不懂，但重點不是這個，是要怎麼看到題目?
利用google 搜尋  "zerojudge 題號 "  ， ex: "zerojudge a001"
然後點庫存頁面，就可以看到以前的記錄了

*再來就是重點的，要怎麼把我寫好的code去judge呢?
只要輸入下面那一行就可以直接Judge了

http://zerojudge.tw/SubmitCode?problemid=題號

ex: http://zerojudge.tw/SubmitCode?problemid=a001

其實他的網站只有讀題目內容有錯誤，其他的部分還是正常的
希望可以幫助有遇到相同問題的人，最好是快點修好比較重要啦，畢竟我的方法是治標不治本。
