Hey
You should not give any outputs like “ENTER THE NUMBER OF TEST CASES:” , “ENTER COORDINATE” etc.

Judge considers it as an output, while comparing your output with the correct answer and that is the reason you are getting a wrong answer. So try removing such instructions and submit your code.

Also you should not use “WRONG DATA! ENTER AGAIN!” because constraints that are mentioned in the question will be followed strictly in the test cases.

Thanks indeed! Will surely help me. :slight_smile:
