Nemotron-LeetCode-coding-clean-3.2k
Nemotron + LeetCode Coding Clean 3.2k
3,200 distinct training problems, seed 42, intended for Python coding reinforcement learning. This is a training mix, not a held-out benchmark. It combines the pinned default train Parquet split of Nemotron-RL-coding-competitive_coding with the train JSONL of LeetCodeDataset.

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.
