I've reviewed the problem statement and it's already in good LQDOJ markdown format. The formatting follows all the required rules:

1. LaTeX math notation is correctly used with $ for inline math
2. Section headers use #### prefix
3. Constraints and input specifications are in bullet points with - prefix
4. Test cases use the correct admonition syntax with !!! question, ???+ "Input", and ???+ success "Output"
5. All spacing and indentation is correct
6. Numbers are properly formatted in LaTeX
7. Lists are properly indented
8. No spurious spaces in LaTeX expressions

The only possible enhancement would be adding explanatory notes for the example using ??? warning "Note", but since the original doesn't include explanations, we should keep it as is to maintain the exact same content.

Would you like me to suggest any specific formatting improvements or would you like to keep it exactly as shown?
