LeetCode multilingual benchmark dataset
LeetCode problems for the msl-multilingual-self-learning benchmark, flattened to
one row per (problem, language) in 9 languages, stored as data/<split>/<lang>-NNN.jsonl.
Each row has the interface for its language (from LeetCode's code snippets),
the shared canonical_tests (Python asserts from newfacade/LeetCodeDataset),
the problem_description (from the LeetCode page) and metadata.
Tests that break the problem's Constraints, do not fit a… See the full description on the dataset page: https://huggingface.co/datasets/neulab/leetcode.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.
