各位大大晚安~
事情是這樣的我現在有一個1A2B遊戲
但是我怎麼找都找不到BUG的地方 QQ(BUG已解決...現在卡在降不到50次以下~已經想了一個晚上....)
三個程式碼:

可是我看都沒有QQ

老師指定說:
使回合數降到至少50回合以內(寫在AlBullsCows.class裡面的public int [ ] GenerateNumber( ){ },僅能改這個部分，其它的部分是題目預設的，不能改)

但是我還卡在BUG的地方~不知道有沒有大大可以指點...QQ

感激不盡

-----------------
重貼之後可以RUN了...
但是...還是不在50回內

看起來是演算法的問題呀, .. 別試著用暴力破解呀, 想想自己如果自己要生一套公式來玩這猜數字會怎麼玩
給你一個簡單版的想法, 在允許猜重覆數字的情況下, 先用1111,2222這種方式找出完全沒中的隨意一個號碼(最多應該5次就可以找到), 然後用 1***,2***的方式找到1A, 就換下一組 *1**, *2**, .. 連做4次就有哩

0.0還是只想的到暴力破解....因為老師說只能改寫在AlBullsCows.class裡面的public int [ ] GenerateNumber( ){ },僅能改這個部分，其它的部分是題目預設的，不能改..qq

海綿寶寶 iT邦大神 1 級 ‧ 2021-06-26 15:17:14 檢舉

我測了你的版本
第一次(roundnumber=0)時
你的int [][]answerBase=new int[5040][4];是設定成不同數字
但第二次以後
answerBase 都是 0000
我就沒有繼續往下 trace 下去了
實在沒什麼力氣看這麼長的程式

這個CheckInputNumber怎麼感覺有點笨...

所以是要寫一個程式去猜結果?
看起來4個數字是不重複的(跟我原本的印象一樣),
如果是用人來猜的話,
我記得平均大約10次就可以解出來.

看更多先前的回應...收起先前的回應...

那個GenerateInputNumber也有點奇怪,
為什麼看起來像是先寫數字,
然後最後才產生答案??

我重貼後就可以~
因為老師說只能改寫在AlBullsCows.class裡面的public int [ ] GenerateNumber( ){ },僅能改這個部分，其它的部分是題目預設的，不能改..qq光卡在這裡就超然想的阿~

這東西有點麻煩需要花時間,
你先一行一行看把整個程式的流程看清楚吧...

我把我說的方法實作完了, 你參考看看

其實不太需要管你老師寫的其他部份, 你需要思考的是如何利用現有的3個array去推算已知的訊息, 當然這不是好的解答, 因為我完全沒用到B的相關訊息, 給你作個參考
