你提供的这段提示是关于需要API密钥的信息，和前面“编写一个函数 fun(，求一个不超过五位的十进制整数各位数值的和”无关哦。就前面的需求，我为你生成的标题是：揭秘！编写求不超五位整数各位数值和的函数fun

You didn't provide an API key. You need to provide your API key in an Authorization header using Bearer auth (i.e. Authorization: Bearer YOUR_KEY), or as the password field (with blank username) if you're accessing the API from your browser and are prompted for a username and password. You can obtain an API key from https://platform.openai.com/account/api-keys. ######[AI写代码神器 | 363点数解答 | 2024-03-09 14:36:59]
