[問題] 用Java寫ACM題目,輸入的問題
最近在練習用Java寫程式，就找了一題簡單的ACM第476題來解解看.
code如下
http://140.116.5.200/~p7694410/ACM476.txt
答案應該沒錯，程式submit前我也把public class的public去掉了
，但還是出現compile error
後來看ACM寫到submit Java有它的限制：
http://online-judge.uva.es/board/viewtopic.php?t=7429
摘錄：
The Java programs submitted must be in a single source code (not .class) file.
Really, they are compiled and run as native applications using the gcj
compiler. They must read and write the standard input/output, as the other
languajes. Note that java::io use is restricted; this implies that some
features (for example, to create a DataInputStream variable with System.in as
argument, in order to use readLine to read strings from the standard input) are
not available.
所以我的code會compile error是因為用System.in及readLine的原故，
我對Java還不是很熟...
想請教一下各位高手我該怎麼修改輸入的寫法？ 才能通過ACM java compiler的考驗，
另外想請教ACM的Java compiler：gcj也同步支援到jdk5.0嗎？
感謝回答..
