Pls help me debug the code

Why on inserting ‘\0’ character at the end of string “ans” all test cases are getting wrong and on removing it all TCs are getting passed?

@Senjuti256
that wont matter.must be something with backend
to make your code work add c-- to your while(c>0) loop .
that will pass all the test cases
Mark your doubt as resolved if u are satisified :slight_smile:
