In tic-tac-toe, the move with which you have the highest possibility of winning is determined. With the following procedure, the state transitions of the game are represented as a tree structure, and the evaluation value of each node other than the root is calculated. As a result, the move with the highest evaluation value among the children of the root is regarded as the move with the highest possibility of winning. A move selected by you is represented by ○, and a move selected by the opponent is represented by ×.

When the game is in the state of the root at the top of the figure, there are three moves you can select. Of them, the evaluation value of the child pointed to by A is A, and the evaluation value of the child pointed to by B is B.

The program converts a Unicode code point to a UTF-8 encoding. In this question, “(16)” after a numerical value indicates a hexadecimal value.
Each Unicode character is given an integer value that is known as a code point. UTF-8 is one of the methods of encoding Unicode characters, and a character with a code point that ranges from 800(16) to FFFF(16) is encoded to a 3-byte value as below.
Let the bit pattern with a 3-byte length be 1110xxxx 10xxxxxx 10xxxxxx. The code point represented in binary is stored right-justified in the underlined “x” positions in the bit pattern, and 0 is stored in any leftover “x” positions. This 3-byte value is the UTF-8 encoding.
For example, when 3042(16), the code point of the hiragana character “あ”, is represented in binary, it is 11000001000010. When this is stored right-justified in the “x” positions in the bit pattern shown above, it is 1110xx11 10000001 10000010. When 0 is stored in the two leftover “x” positions, the UTF-8 encoding of “あ”, 11100011 10000001 10000010, is obtained.
The function encode converts a Unicode code point that is passed as an argument to UTF-8 encoding, and returns an integer-type array that stores it one byte per element in order from the start. It is assumed that only an integer value that ranges from 800(16) to FFFF(16) is passed to encode as an argument.
