### 分石子【[链接](https://www.nowcoder.com/questionTerminal/1ea5b4eaeff841a4918931791b000756)】

有N堆石子，第 $$i$$ 堆一共有 $$a\_i$$ 个石子。可以对任意一堆石子数量大于1的石子堆进行分裂操作，分裂成两堆新的石子数量都大于等于1的石子堆。现在需要通过分裂得到 m 堆石子，求这 m 堆石子的最小值最大可以是多少？

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://mqjyl2012.gitbook.io/algorithm/algorithm-thinking/dichotomy.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
