代码编辑区域Code Editing Areas

编辑器由以下区域组成，各司其职：

The editor is made up of the following areas, each with its own role:

• Header 区域Header：在代码执行前添加的代码片段（如导入语句、函数定义等）code added before execution (imports, function definitions, etc.)
• 代码区域Code area：编写主要代码where you write your main code
• Footer 区域Footer：在代码执行后添加的代码片段（如清理代码、测试代码等）code added after execution (cleanup, tests, etc.)
• 输入区域Input area：提供标准输入（stdin）provides standard input (stdin)
• 输出区域Output area：显示程序执行结果shows the program output
• 调试区域Debug area：显示执行过程中的调试信息shows debug information during execution

参数设置Parameter Settings

Footer（尾部）Footer

• 在代码执行后添加的代码code added after execution
• 常用于清理资源、运行测试、输出结果等commonly used for cleanup, running tests, and printing results
• 示例：调用主函数、清理内存等e.g., calling the main function, freeing memory

· 参数（Arguments）Arguments

传递给程序的主函数参数，例如：Arguments passed to the program’s main function, for example:
