| # 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 declared type in some |
| language, or expect inf/nan were removed; problems that take trees or linked |
| lists, modify their input in place, or kept fewer than 10 tests were dropped. |
| The test split also drops problems with several valid answers or whose text |
| refers to a figure. Where answers may come in any order or are decimals, |
| the asserts call `answers_match` (defined at the top of the test source), and |
| `canonical_tests.comparison` says which rule applies ("unordered", "float" or "exact"). |
| `public_tests` holds the inputs of LeetCode's Testcase panel (one string per |
| case, one JSON value per line in parameter order; LeetCode publishes no |
| outputs), and `hints` the page's hints as plain text. |
| `reports/dropped.md` lists every dropped problem and test count, and |
| `reports/<split>.json` has the details. |
|
|
| ## Splits |
|
|
| - `train`: 2103 problems x 9 languages = 18927 rows (2641 in the source dataset) |
| - `test`: 191 problems x 9 languages = 1719 rows (228 in the source dataset) |
|
|
| ## Load |
|
|
| ```python |
| from datasets import load_dataset |
| train = load_dataset("neulab/leetcode", split="train") |
| test = load_dataset("neulab/leetcode", split="test") |
| python_rows = test.filter(lambda r: r["language"] == "python") |
| ``` |
