    Since the original data were weak, 3 more test cases were added to the second batch.

      An additional test case was added to both subtasks, making 1 new test case for the first batch and 4 new test cases for the second batch.

    is linear time complexity too slow?

      Linear time is intended, your solution runs in quadratic time (checking string equality is linear in the length of the string)

      I think it's due to your second forloop. I can't pinpoint your exact issue but try troubleshooting with the test case BAHAHABA HAHA

    For the constraints, do they apply to the input strings or the output string?
