? ? ? ?最近游戲王OCG出了一張新卡（劃掉，等我發(fā)專欄的時候應(yīng)該不是新卡了）超量支援卡，編號系覺醒。對，就是下面這貨。

以下是K語言時間。

? ? ? ?編號系覺醒，通常魔法，無限制，效果是①：從額外卡組特殊召喚的怪獸只有對方場上才存在的場合才能發(fā)動。從額外卡組選4只「No.」XYZ怪獸（相同階級最多1只）?！窷o.」數(shù)值和那4只的合計相同的1只「No.」XYZ怪獸當(dāng)作XYZ召喚從額外卡組特殊召喚，把選的怪獸全部在那只怪獸下面重疊作為XYZ素材。只要這個效果特殊召喚的怪獸在自己場上表側(cè)表示存在，自己不是「No.」XYZ怪獸不能特殊召喚。

?? ? ? 大伙一看，好，一卡四素材槍王，一卡ll打臉主階二變天庭號……想法都很不錯，問題是要把一個數(shù)拆成四個數(shù)之和，所對應(yīng)的「No.」怪獸的階級還要各不相同。那些主流的相加方法很快就會有大佬總結(jié)出來，但對于整活玩家（比如命運獅子特殊勝利）來說，這個拆解是個艱難的過程。本人利用僅有的C#知識（其實是C++知識，除了用了C#的語法，一個Class都沒有寫）寫了一段程序（因為是專用程序，沒有任何可拓展性，我會把屎山代碼放在評論區(qū)）把「No.1」到「No.107」的拆分方法全部扒了出來（根據(jù)2022年1月表），接下來就是運行結(jié)果：

1 is unable to xyz.

2 is unable to xyz.

3 is unable to xyz.

4 is unable to xyz.

5 is unable to xyz.

6 is unable to xyz.

7 is unable to xyz.

? ? ? ?看到這里的小伙伴們?nèi)绻皇菫榱私鉀Q以后整活方便的話已經(jīng)可以點個收藏走人了（可以順手點個贊就更好了），接下來就是程序的原理部分了。

? ? ? ?我一開始的想法是對自然數(shù)做拆分然后判斷是否可以出現(xiàn)在不同階級，后來我發(fā)現(xiàn)有的「No.」還呆著禁卡表里（如暗物質(zhì)，色支），有的占據(jù)多個階級（如「No.39」，有1、4、5、6四個階級），判斷函數(shù)非常惡心。于是我反其道而行之，直接按照現(xiàn)有的卡分好階然后將所有求和方式都列出來，這樣雖然做了許多無用功（同一個「No.」的每一種正確拆分都運算過，但只保留了一個），但這樣把一個求解型問題轉(zhuǎn)化為一個驗證型問題還是舒服多了。最后就是我的8個for循環(huán)的屎山參觀了。
