@buzhidao 别人求助你发个自己代码有啥用啊

by _buzhidao_ @ 2023-05-07 13:13:42

@Franz_Liszt 那题解写代码有什么用啊

by __er @ 2023-05-07 13:16:35

@buzhidao 题解有思路，你没有思路有什么用啊

by __er @ 2023-05-07 13:17:13

那是对思路的实现，你是什么啊？

动不动甩个代码显得您架子很大？

@__er 我懒不行吗？

by _buzhidao_ @ 2023-05-07 13:27:19

@__er 多管闲事

by __er @ 2023-05-07 13:28:19

@buzhidao 没那个闲工夫建议别看

by _buzhidao_ @ 2023-05-07 13:29:41
