HumanEval-LeetCode Input-Only
本数据集由 LeetCode 题目自动转换而来，目标是生成 HumanEval 风格的 Input-Only 提示（prompt）。每条样本包含题目描述与函数签名，描述中的 Input/Output 被转换成 >>> func(...) / >>> output 的交互式示例，便于直接用于代码生成评测或训练。
数据格式
每行是一个 JSON 对象（JSONL）：
task_id：题目唯一标识
prompt：包含函数签名与 docstring 的完整提示
示例字段：
task_id: string
prompt: string
生成流程（概述）
读取 LeetCode 题目（题目描述 + starter code）。
提取函数名。
将题目描述中的 Input/Output 转为：
>>> func(inputs...)
>>> output
输出为 JSONL。

Cleaned HumanEval-LeetCode Dataset
Dataset Description
这是一个经过预处理的 LeetCode 代码生成数据集，源自 ShwStone/humaneval-leetcode。
Data Preprocessing (清洗逻辑)
为了直接用于大模型 SFT 训练，原始数据经过了以下清洗：
Type Hinting: 根据代码内容，自动注入了 typing (List, Dict, etc.) 和 collections (deque, defaultdict) 的引用。
Class Removal: 移除了 class Solution 外壳，将代码转换为纯函数形式。
Refactoring: 移除了 self 参数，修复了缩进。
Docstring Repair: 修复了 doctest 中的函数调用名称。
Data Structure
task_id: 题目唯一标识符。
