                Reference solution

                The Judge runs this trusted solution on each test input to produce the answer.

                Test dataset

                Add inputs one by one or upload text files. Expected output is optional with a reference solution.

                File typePlain text files: .txt, .in, or .input.
                Input styleOne file is one complete stdin test. Write values with spaces or line breaks exactly as the contestant program reads them.
                Output styleUse plain text stdout. A reference solution generates it; enter an answer key only when that option is selected.

                No test inputs yet. Add the first one.

                Choose Deterministic coding, write the reference solution, add the test dataset, check the contract, and save. Premium stores the definition; the open-source Judge executes it.
