# SortAlgorithmOverview

아래는 정렬 알고리즘들의 시간 복잡도(최선/평균/최악), 추가 메모리 사용, 특징을 정리한 표입니다.

| 정렬 알고리즘 |                시간 복잡도 (최선 / 평균 / 최악) | 추가 메모리 사용 | 특징                |
| ------- | -----------------------------------: | --------: | ----------------- |
| 선택 정렬   |                O(n²) / O(n²) / O(n²) |      O(1) | 교환 횟수가 적지만 성능이 느림 |
| 버블 정렬   |                 O(n) / O(n²) / O(n²) |      O(1) | 인접한 요소를 비교하며 정렬   |
| 삽입 정렬   |                 O(n) / O(n²) / O(n²) |      O(1) | 거의 정렬된 경우 빠름      |
| 퀵 정렬    |      O(n log n) / O(n log n) / O(n²) |  O(log n) | 평균적으로 매우 빠름       |
| 병합 정렬   | O(n log n) / O(n log n) / O(n log n) |      O(n) | 안정 정렬, 추가 공간 필요   |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://krjaeh0.gitbook.io/j-log/programming/cs-fundamentals/overviews/datastructuresalgorithms/sortalgorithmoverview.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.
