explanation: The document contains a problem statement and a test suite for a solution to the problem. The problem is to find the biggest empty box (submatrix) in a given matrix. The test suite includes four test cases, each with input and expected output, to verify the correctness of the solution.
distilabel_metadata.content: Evaluate the user given text extract and determine if it contains a math question and optionally and answer to this question.
  
  Output rules:
  
  1. Briefly describe the document and mention if it contains a question or a question and answer.
  2. Finalize the output with: Label: no-question,question,question-and-answer,multiple-question,multiple-question-and-answer
