LeetCode Code-Gen Dataset — C++
4025 rows. Given a problem statement, its input/output examples, and a
required algorithm/technique, generate a correct C++ solution.

Agent trace dataset
Decoding the literal token IDs
The prompt_token_ids / completion_token_ids / logprobs columns are the
verbatim tokens the serving engine emitted, stored PER AGENT STEP as a
list-of-lists (one inner list per turn). To turn them back into text you MUST
use the exact tokenizer the model was served with — a generic same-family
tokenizer will decode word tokens to garbage.

Bienvenue sur la base de données Translation_go_into_cpp.
Ce dataset regroupe des traductions de code en trois langages de programmation : Go, Python et C++.Chaque ligne contient un script go, et une traduction de celui ci, soit en python, soit en C++.
L'objectif principal de ce dataset est de fournir une base propre et nettoyée pour l'entraînement
de modèles de type LLM (Large Language Models) dans des tâches de traduction Go ↔ C++.

Cpp-Math: A Math-to-C++ Instruction-Tuning Dataset
Dataset Overview
The Cpp-Math dataset is designed for fine-tuning models to translate mathematical problems into C++ code. It focuses on evaluating the ability of language models to generate accurate and executable C++ code from mathematical expressions or problem statements. The dataset is particularly useful for benchmarking models on tasks that require both mathematical reasoning and programming skills.
