CodeForces

We use Stdio input/output format here. For example, for the task to calculate the sum of a list, the input and output are in the following format:
```python
input = "5\n1 2 3 4 5\n"
output = "15"
```
CodeContests and CodeForces are using this format, however, MBPP and part of LiveCodeBench are using functional input/output format, such like
```python
assert sum_function([1, 2, 3, 4, 5]) == 15
```
In this project, we have converted the the functional format to the Stdio format to achieve consistency.

本数据集采用标准输入输出（Stdio）格式。以列表求和任务为例，其输入输出格式如下：
python
input = "5
1 2 3 4 5
"
output = "15"

CodeContests与CodeForces均采用此类格式；而MBPP与部分LiveCodeBench则采用函数式输入输出格式，示例如下：
python
assert sum_function([1, 2, 3, 4, 5]) == 15

本项目已将函数式输入输出格式转换为标准输入输出格式，以实现格式统一。
