Doocs LeetCode Solutions
LeetCode problems with solutions in many programming languages, built from the Doocs LeetCode repository. Each solution comes with the approach name, the reasoning that leads to it, and an explanation with complexity analysis. The dataset is meant for fine-tuning and evaluating code generation models.
The dataset is regenerated monthly from the latest Doocs commit by the leetcode-dataset-generator tool.

Original data -> LimYeri/leetcode_with_youtube_captions
The original ['cc_content'] column had tokens that were too long and contained a lot of repetition, which necessitated summarization.
Consequently, our team (Project Team: CodeMind) summarized the ['cc_content'] column data using the Chain of Thought (CoT) technique with the gpt-3.5-turbo-0125 & gpt-4-turbo-2024-04-09 model. -> new column ['Summary']
