近日偶遇 舒涵老師 《國學*周易》4天免費試聽課，帶著一顆好奇心，看了2晚直播；

第1課入門周易基礎知識；

第2課講梅花易數；

聽完梅花易數，突來靈感，隨機報2個數字，根據公式測算兇吉；感覺就是一道編程題，于是第2天工作，花了一個上午也出了公式，下面展示一下執行效果。

• 報數：32，57；得到以下執行結果：
• >>>> 說明這是 上課出的題目，此處用于驗證個人的公式對不對！

用 ? > ?
---------
體 ? > ?

輸入(32,57) ===> [原卦](??) ===> [變卦](??)
測算(32,57) ===> 依始運勢：大吉，事易成！ 未來走勢：小兇，事難成！
MSG(32,57) ===> At the beginning: very good, it is so easy! At the end: I think it is difficult!

• 報數：22，44；得到以下執行結果：
• >>>> 說明這是 2022-08-02 ?佩洛西竄訪中國臺灣地區的飛機落地時間，相信未走勢完全有利于中方

用 ? > ?
---------
體 ? > ?

輸入(22,44) ===> [原卦](??) ===> [變卦](??)
測算(22,44) ===> 依始運勢：大吉，事易成！ 未來走勢：大吉，事易成！
MSG(22,44) ===> At the beginning: very good, it is so easy! At the end: very good, it is so easy!

• 報數：18，22；得到以下執行結果：
• >>>> 說明公司聚會常去 十八二十二 這家店，猜想此店老板有風水學問，這2個數字肯定大吉，果不其然！！

用 ? > ?
---------
體 ? > ?

輸入(18,22) ===> [原卦](??) ===> [變卦](??)
測算(18,22) ===> 依始運勢：大吉，事易成！ 未來走勢：大吉，事易成！
MSG(18,22) ===> At the beginning: very good, it is so easy! At the end: very good, it is so easy!
