ok single line: 'NO' This means your output is correct and you pass this test.

      It's accepted. It's not a warning. Checkers will give every test a comment.

      Table of checker verdict to codeforces verdict

      • ok --> Accepted, full mark
      • points 0.xx --> Accepted, xx% of the full mark
      • wrong answer, wrong output format --> Wrong Answer, zero

      single line: 'NO' means that the answer of the problem is a single line which only contains a single word NO.
