Main-main dengan JAVA

Ada soal quiz yang menarik untuk dijawab, nieh. Tanpa berbasa-basi mari kita langsung pada pokok persoalannya.

Begini kira2 ilustrasi dari “maunya soal tersebut”

GDIQuiz01(1000);    //return : 12345*678*910111213*141516*1718192021*....

GDIQuiz02(1000);        //return :    AAAAAAAAAA000
            //        AAAAAAAAAA000
            //        AAAAAAAAAA001
            //        .............
            //        AAAAAAAAAA999
            //        AAAAAAAAAB000
            //        .............
            //        ZZZZZZZZZZ999

Ini Jawabannya,

1. Method GDIQuiz01(int numParam)

<pre>private static int[] arrMagicVar = {3,5};
