+guidelines:
+
+### DOs
+
+* **DO** create one pull request per Issue, and ensure that the Issue is linked
+in the pull request. You can follow the [Pull Request Template](PULL_REQUEST_TEMPLATE.md)
+for this.
+
+* **DO** follow our [Coding and Style](#style-guidelines) guidelines, and keep code
+changes as small as possible.
+
+* **DO** include corresponding tests whenever possible.
+
+* **DO** check for additional occurrences of the same problem in other parts of the
+codebase before submitting your PR.
+
+* **DO** link the issue you are addressing in the pull request.
+
+* **DO** write a good description for your pull request. More detail is better.
+Describe *why* the change is being made and *why* you have chosen a particular solution.
+Describe any manual testing you performed to validate your change.
+
+### DO NOTs
+
+* **DO NOT** merge multiple changes into one PR unless they have the same root cause.
+* **DO NOT** merge directly into the master branch.
+
+> Submitting a pull request for an approved Issue is not a guarantee it will be approved.
+> The change must meet our high bar for code quality, architecture and performance.
+
+## Making changes to the code
+
+### Preparing your development environment
+
+To learn how to build the code and run tests, follow the instructions in the [README](README.md).
+
+### Style guidelines
+
+The code in this project uses several different coding styles, depending on the
+age and history of the code. Please attempt to match the style of surrounding
+code as much as possible. In new components, prefer the patterns described in the
+[C++ core guidelines](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines).
+
+### Code formatting
+
+***Run clang-format***
+
+Use the following commands from the project's root directory to run clang-format
+(must be installed on the host system).
+
+**1. Run the CMake target for `clang-format`:**
+
+```bash
+cmake --build build --target clang-format
+```
+
+**2. Using clang-format:**
+
+```bash
+# !!! clang-format does not run recursively in subdirectories !!!
+# for each .cpp file modified
+clang-format -i *.cpp
+
+# for each .h file modified
+clang-format -i *.h
+
+# for each .hpp file modified
+clang-format -i *.hpp
+```
+
+**3. Using TheLartians' Format.cmake:**
+
+```bash
+cmake -Htest -Bbuild/test
+
+# view changes
+cmake --build build/test --target format
+
+# apply changes
+cmake --build build/test --target fix-format
+```
+
+See [Format.cmake](https://github.com/TheLartians/Format.cmake) for more options.
+
+### Testing
+
+Your change should include tests to verify new functionality wherever possible.
+Code should be structured so that it can be unit tested independently of the UI.
+Manual test cases should be used where automated testing is not feasible.
+
+### Git workflow
+
+The core principle of the project, when it comes to Git workflows is that the
+`master` branch should always be in a healthy state which is ready for release.
+Every commit on master should be deployable on push. To ensure this, pull request
+**must not** be made directly on master. **Each change** should either be made in
+the **development branch** (named a variation of development, i.e. `dev`) or in a
+separate branch, named as a short summary of the change.
+
+If your change is complex, please clean up the branch history before submitting a
+pull request. You can use [git rebase](https://git-scm.com/book/en/v2/Git-Branching-Rebasing)
+to group your changes into a small number of commits which we can review one at a
+time.
+
+When completing a pull request, we will generally squash your changes into a single
+commit. After confirming that the change works as intended, the branch *might* be
+deleted, in order to prevent branch polluting. Please let us know if your pull request
+needs to be merged as separate commits.
+
+### Continuous Integration
+
+For this project, CI is provided by [GitHub Actions](https://github.com/features/actions),
+with workflows found in the [`.github/workflows` folder](.github/workflows). Workflows
+are run automatically on every commit made on the master branch, unless told to skip
+for that particular commit.
+
+To skip CI runs on a particular commit, include either `[skip ci]` or `[ci skip]`
+in the commit message.
+
+```bash
+# an example of a commit message that would not trigger CI workflows
+git commit -m "my normal commit message [skip ci]"
+# or
+git commit -m "my normal commit message [ci skip]"
+```
+
+## Review process
+
+After submitting a pull request, members of the team will review your code. We will
+assign the request to an appropriate reviewer (if applicable). Any member of the
+community may participate in the review, but at least one member of the project team
+will ultimately approve the request.
+
+Often, multiple iterations or discussions will be needed to responding to feedback
+from reviewers. Try looking at [past pull requests](https://github.com/filipdutescu/modern-cpp-template/pulls?q=is%3Apr+is%3Aclosed)
+to see what the experience might be like.
+
+## Contributor License Agreement
+
+Before we can review and accept a pull request from you, you'll need to sign a
+Contributor License Agreement (CLA). The CLA ensures that the community is free
+to use your contributions. Signing the CLA is a manual process, and you need to
+do it for each pull request made. This is done by checking the boxes in the
+[Pull Request Readiness Checklist of a Pull Request](PULL_REQUEST_TEMPLATE.md#Pull-Request-Readiness-Checklist).
+
+### IMPORTANT
+
+***Checking the aforementioned boxes means that you agree to provide your change
+and/or code FREE TO USE and SUBJECT TO CHANGES for the entire community!***
+
+You don't need to sign a CLA until you're ready to create a pull request. When your
+pull request is created, it is reviewed by a team member which, if the change is
+trivial (i.e. you just fixed a typo) will be labelled as `cla-not-required`.
+Otherwise, it's classified as `cla-required`, if not already signed.

+**IMPORTANT: Please do not create a Pull Request without creating an issue first.**
+
+*Any change needs to be discussed before proceeding. Failure to do so may result
+in the rejection of the pull request.*
+
+Please provide enough information so that others can review your pull request. You

+
+Explain the **details** for making this change. What existing problem does the pull
+request solve?
+
+Ex:
+
+1. If you "Added a/changed the function to do X", explain why:
+
+    * it is necessary to have a way to do X.
+    * if there already exists a way, why is your implementation better
+
+2. If you "Fixed bug/error in X", explain:
+
+    * what was the bug/error (if you already made an issue, please link to it here)
+    * how does your implementation fix the issue
+
+### Code style and formatting
+
+Check the [Contributors Style Guidelines section](CONTRIBUTING.md#Style-guidelines)

+# A*寻路算法大作业
+
+## Getting Started
+
+These instructions will get you a copy of the project up and running on your local
+machine for development and testing purposes.
+
+### Prerequisites
+
+This project is meant to be only a template, thus versions of the software used
+can be change to better suit the needs of the developer(s). If you wish to use the
+template *as-is*, meaning using the versions recommended here, then you will need:
+
+* **CMake v3.15+** - found at [https://cmake.org/](https://cmake.org/)
+
+* **C++ Compiler** - needs to support at least the **C++17** standard, i.e. *MSVC*,
+*GCC*, *Clang*
+
+> ***Note:*** *You also need to be able to provide ***CMake*** a supported
+[generator](https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html).*
+
+### Installing
+
+It is fairly easy to install the project, all you need to do is clone if from
+[Gitee](https://gitee.com/fun-sun/iTraining).
+
+If you wish to clone the repository, rather than generate from it, you simply need
+to run:
+
+```bash
+git clone https://gitee.com/fun-sun/iTraining
+```
+
+测试C++大作业：
+```bash
+cmake --build build --config Release
+build/test/tmp_test_Tests 
+```
+标准测试提供了三个样例，前两个可以通过，第三个无法到达终点因此无法通过
+随机测试有可能无法通过
