+"""# 谜题训练场开发任务
+
+## 任务概述
+你是一位资深程序员，我需要你帮我实现一个特定谜题的训练场环境类。这个类继承自`Basebootcamp`，用于生成谜题实例并验证解答。
+
+## 背景说明
+我正在开发一系列谜题训练场，每个训练场对应一个特定类型的谜题。训练场类命名为`{PuzzleName}bootcamp`，其中`PuzzleName`是谜题的名称。
+
+每个训练场类主要提供两个核心功能：
+1. 生成该谜题类型的问题实例
+2. 验证用户对问题的回答是否正确
+
+## 技术接口规范
+
+### 类方法实现要求
+
+```python
+class {PuzzleName}bootcamp(Basebootcamp):
+    def __init__(self, **params):
+        \"\"\"
+        请你自定义params，以保存该puzzle相关的参数，例如网格大小等，参数配有默认值
+        \"\"\"
+        pass
+    
+    def case_generator(self):
+        \"\"\"
+        生成谜题实例，提示：为保证谜题有解，可以先生成结果再对结果处理得到谜题
+        返回：一个可JSON序列化的字典（避免包含set等无法通过json.dumps处理的数据结构）
+        \"\"\"
+        pass
+    
+    @staticmethod
+    def prompt_func(question_case) -> str:
+        \"\"\"
+        将case_generator生成的谜题实例转换为文本形式的问题，问题中包含问题背景、对谜题规则的介绍、具体要解决的谜题实例、期望最终答案的格式，
+        例如：你是xxxx，请你解答yyyy，规则如下：yyyy，最终答案放置在：zzzzz
+
+        参数:
+            question_case: 由case_generator生成的谜题实例
+            
+        返回:
+            str: 格式化的问题字符串
+            
+        注意:
+            1. 需考虑问题的格式，以便后续能正确提取
+            2. 问题描述中应包含期望的答案格式说明，以便后续能正确提取，为了避免抽取时匹配出干扰项，请要求模型将答案放在特定标签，如[answer] [/answer]内
+        \"\"\"
+        pass
+    
+    @staticmethod
+    def extract_output(output):
+        \"\"\"
+        从LLM的回复中提取符合格式要求的答案，如有多个，请抽取最后一个，避免使用re.search等只抽取第一个结果的方式。
+        
+        参数:
+            output: LLM的完整输出（包含原始问题和回答）
+            
+        返回:
+            提取的答案，若未找到符合格式的答案则返回None
+        \"\"\"
+        pass
+    
+    @classmethod
+    def _verify_correction(cls, solution, identity):
+        \"\"\"
+        验证提取的答案是否正确，注意一个问题可以能有多个解，按照谜题规则进行检验，不要直接匹配可能的答案。
+        
+        参数:
+            solution: extract_output提取的答案
+            identity: case_generator生成的谜题实例
+            
+        返回:
+            bool: 答案是否正确
+        \"\"\"
+        pass
+```
+
+### 验证评分方法（基类已实现）
+
+```python
+@classmethod
+def verify_score(cls, model_output, identity:dict, format_score=0.1) -> float:
+    \"\"\"
+    验证输出结果并评分。
+    
+    参数:
+        model_output: 模型的完整输出
+        identity: 谜题实例（由case_generator生成）
+        format_score: 答案格式正确时的基础分数
+    
+    返回:
+        float: 评分结果（0-1之间）
+    \"\"\"
+    score = 0. 
+    try:
+        extract_solution = cls.extract_output(model_output)
+        if extract_solution is None:
+            return score
+        else:
+            score = format_score # 格式正确时的基础分数
+        if cls._verify_correction(extract_solution, identity):
+            score = 1.  # 答案完全正确时的满分
+    except Exception as e:
+        # 处理异常情况
+        pass
+    return score
+```
+
+### 使用示例
+
+```python
+# 初始化谜题训练场
+bootcamp = Puzzlebootcamp()
+
+# 生成谜题实例
+case = bootcamp.case_generator()
+
+# 将谜题转换为文本问题
+prompt = Puzzlebootcamp.prompt_func(case)
+
+# 获取LLM对问题的解答
+response = get_response(prompt, \"LLM\")
+
+# 从完整对话中提取答案
+extracted_output = Puzzlebootcamp.extract_output(prompt + response)
+
+# 验证答案并评分
+score = Puzzlebootcamp.verify_score(extracted_output, case)
+```
+
+## 你的任务
+请根据以下谜题描述（谜题描述可能不完整，请先结合你的知识澄清规则），实现一个完整的谜题训练场类：
+
+### 谜题描述
+
+**Masyu Rules Explained:**
+
+1. **Objective:** Create a single continuous loop that passes through all black and white circles on the grid. The loop must not intersect itself or branch, and it moves horizontally/vertically along grid lines.
+
+2. **Black Circles (●):**
+   - The loop **must travel straight through the black circle** (entering and exiting from opposite sides).
+   - **Immediately before and after** the black circle, the loop **must turn 90 degrees**. This means the path segments leading into and out of the black circle are perpendicular.
+   - Example: If the loop approaches a black circle from the north, it exits south, and the path must turn east/west both before entering (north→east/west) and after exiting (east/west→south).
+
+3. **White Circles (○):**
+   - The loop **must turn 90 degrees at the white circle** (entering and exiting from adjacent sides, e.g., north→east).
+   - **Immediately before and after** the white circle, the loop **must travel straight** for at least one segment. No turns are allowed in the cells adjacent to the white circle.
+   - Example: If approaching a white circle from the north, the loop turns east at the circle, then continues east straight for at least one cell.
+
+4. **General Constraints:**
+   - The loop occupies entire grid lines (edges), not cells.
+   - All circles must be traversed, and the loop may pass through empty cells as needed, but it cannot revisit any grid edge.
+   - No diagonals, crossings, or dead ends allowed.
+
+
+请完成上述谜题的训练场环境类实现，包括所有必要的方法。

+Masyu规则:
+1. 必须画一条封闭的单线环，线不能交叉或分叉。
+2. 白珠(○)规则：线必须穿过白珠并在白珠处直行，但必须在白珠的至少一侧转弯。
+3. 黑珠(●)规则：线必须在黑珠处转弯，并在黑珠的两侧直行至少一格。
+4. 线必须穿过所有珠子，但不必经过所有空格。
+
+谜题如下：
+
+{cls.print_masyu_str(identity)}
+
+请给出形成闭环的完整路径，以坐标序列的形式表示。坐标格式为(行,列)，从0开始计数。
+例如：[(0, 0), (0, 1), (1, 1), ..., (0, 0)]
+
+注意：路径必须是一个闭环，所以第一个坐标和最后一个坐标应该相同。

+
+Masyu Rules:
+1. You must draw a single closed loop that doesn't cross or branch.
+2. White pearl (○) rule: The loop must pass straight through white pearls, but must make a turn in at least one of the cells adjacent to the white pearl.
+3. Black pearl (●) rule: The loop must make a turn at black pearls, and must go straight through the next cell in both directions.
+4. The loop must pass through all pearls, but doesn't need to visit all empty cells.
+
+The puzzle is as follows:
+
+{cls.print_masyu_str(identity)}
+
+Please provide the complete path forming a closed loop as a sequence of coordinates. Coordinates are in (row,column) format, starting from 0.
+For example: [(0, 0), (0, 1), (1, 1), ..., (0, 0)]
+
+Note: The path must be a closed loop, so the first and last coordinates should be the same.
