Here are a few common solutions that may help:
- Have you double checked to make sure there are no extra spaces or blank lines in your output? This could be causing your test cases to fail.
- Are you using a different compiler? Check out our Environment page https://www.hackerrank.com/environment for up-to-date information on how we're compiling your code.
- Your code doesn't match the expected output. The output produced by your code must exactly match the output expected by the test case, so something like a spelling error in your output will cause you to fail the challenge.
We encourage you to post your issue in the discussion area, which is a forum moderated by HackerRank. You may find other users who have come across the same issue and received a resolution.
