下面是程序的完整结构图：

+------------------------+
|         main()         |
+------------------------+
        |
        v
+------------------------+
|         init()         |

        |
        v

|         print()        |

        |
        v

|         solve()        |

其中，`init()` 函数用于随机生成迷宫，`print()` 函数用于输出迷宫，`solve()` 函数用于求解迷宫，`print_path()` 函数用于输出路径。在 `main()` 函数中，我们首先调用 `init()` 函数生成迷宫，然后调用 `print()` 函数输出迷宫。接着，调用 `solve()` 函数求解迷宫，最后调用 `print_path()` 函数输出路径。
