In your coding Questions, the “Wrong Answer” status of your test cases implies that your program or coding logic is unable to produce the exact expected output for the test cases due to various reasons.
Some primary causes and possible resolutions are explained below:
|Mismatch of input and output values||
Test cases fail when the input passed by your code may not be in the exact format as expected by the test case. Also, when the output returned by your code is not the exact expected output format, you will see a “Wrong answer” status.
|Question comprehension -handling edge cases||
If some of your Test cases have passed, but you see a "Wrong Answer" status for others, it may imply that your coding logic is unable to handle the corner cases expected from the solution. For example, test cases which validate boundary values may fail if you've not written the logic to check for boundary values.
|Issues with code formatting or package guidelines||
Check for other issues in your code such as:
It is recommended that you verify the above-mentioned causes and also debug your solution to identify the issues. Refer to the following topics for information about debugging your code:
