※ 引述《didii7to (86)》之銘言:
: 首先 請各位拿起紙和筆...好囉
: 開始解說
: 1.(4,4)&(4,5)其中1個是8
: 2.當(4,4)=8時 導出(6,6)=7
: 3.當(4,5)=8時 也導出(6,6)=7...自然得知不為6
: 4.證明(4,6)不為7
: 5.得証(7,6)=6
: 接下來就可以拿起各位的紙筆模擬囉~
講解一下第3點
當(4,5)=8 時 (7,5)=6 [有人有疑問解不是(7,6)=6嗎?] 先別急 繼續往下解
(7,6)=9 (3,6)=5 (6,6)=7
雖然過程中(7,5) =6 跟正解 (7,6) =6 互斥 但由於 (4,4)&(4,5)其中1個是8
而不管哪個是8 最終(6,6)都會是7....
這樣有明白嗎@___@?
