根据个人习惯，以下采用叙事格式为：
code
# output修订如下：
C001 调试用途，不需提供；
C002 此处省略代码N行，仅输出Hello world，可得分30；
C003 注意：/tcdata/num_list.csv无表头；
C004 注意：TOP10 若包含重复值；
以下示例环境：CentOS
yum install -y docker
# ...service docker restart
# Redirecting to /bin/systemctl restart docker.servicedocker ps

## 从天池基础镜像构建

## 把当前文件夹里的文件构建到镜像的根目录下
ADD . /
## 指定默认工作目录为根目录（需要把run.sh和生成的结果文件都放在该文件夹下，提交后才能运行）
WORKDIR /
## 镜像启动后统一执行 sh run.sh
CMD ["sh", "run.sh"]
