Data Preview
The data available in this preview contains a 10 row dataset:
- Sample Dataset ("sample"): This is a subset of the full dataset, containing data from 2023.
To view full dataset, download output_dataset.parquet
. This contains data from 2011 to 2023.
Fields
The dataset include the following fields:
name
(string)year
(string)round
(string)statement
(string)input
(string)solution
(string)code
(string)sample_input
(string)sample_output
(string)images
(array of base64 image strings)
This dataset contains every Facebook/Meta Hacker Cup problem from 2011 through 2023. For each problem, you'll find these files:
<problem_name>.md
: The problem statement formatted in Markdown<problem_name>.in
: The full input file<problem_name>.out
: The full output file- Note that some problems accept multiple possible outputs, in which case the full output file is simply an example of an output that would be accepted
<problem_name>_sample_input.txt
: The sample input provided by the problem statement<problem_name>_sample_output.txt
: The sample output provided by the problem statement
Note that for problems from 2011 thorugh 2019, the problems were initially typeset in html. For those problems you can find:
<problem_name>.html
: The problem statement formatted in HTML
For these problems, the Markdown version of the statement (<problem_name>.md
) was automatically generated from the HTML version and may contain errors.
For some problems, written solutions/analyses are available:
<problem_name>.sol.md
** For some problem, code solutions are available:<problem_name>.(cpp|py|java)
Some problems contains references to images that look like this:
{{PHOTO_ID:<photo_id>}}
, example:{{PHOTO_ID:923060468192530}}
In the same folder as the problem statement, you can find <photo_id>.jpg
or <photo_id>.gif
Starter Kits
Some quick start solutions for working with this data are available at HackerCupAI Repo. Some frameworks include:
The samples show basic steps for data ingest, generating solutions, and evaluation. For an example of data ingest, check out this example
Notes
- Solutions prior to 2019 do not contain markdown solution files.
- The 2019 markdown solutions are not included in the dataset but can be found in
.cpp
files.
