/*小明想在控制台上输出 m x n 个方格。
比如 10x4的，输出的样子是：
+ -- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +
| | | | | | | | | | |
+-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +
| | | | | | | | | | |
+-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +
| | | | | | | | | | |
+-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +
| | | | | | | | | | |
+-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +-- - +
