Candidates will understand the utility of the Test platform.
If you made a mistake in your program and already clicked on the Save and Submit button, you can still make changes to your program.
Check the status of the Test cases to ensure that your program is working successfully.
If the status of the Test cases says Wrong Answer, you can edit your program and click on the Save and Submit button again.
You can click on Save and Submit as many times as you want. WeCP always considers the best submission (i.e the submission that will fetch maximum marks).
