◆Code Game
There is a text consisting of only the letters A, and B. You are going to
play a game with your friend. Without seeing the text, you and your friend
both will choose a three-letter code. The one whose code appears first will
be the winner.
If your friend chooses the code ABA, what should your code be in order to
maximize your probability to win the game?
Notes:
* A and B have the same probability to exist anywhere in the text.
* All possible three-letter codes that can be created with A and B are
included in the text.
* There are no blanks between the letters.
有一段文字只含字母 A 跟 B。
你跟朋友玩這麼一個遊戲:在不看這段文字的前提之下,你們各自提出一個三字母組。
在此段文字中誰的三字母先出現誰就贏了。
若你的朋友選擇 ABA,則你選擇哪個三字母組贏的機率最高?
註:
* 此段文字中 A 跟 B 的出現機率相等。
* 所有可能的三字母組合都會在此段文字中出現。
* 此段文字中字母之間沒有空白。
