Challenges questions

in some question a constraint is given so do we have to follow that constraint or is it a condition not to be followed.
basically what is the meaning of constraint in the questions.

@yutikakhanna hey yutika you must follow the constraints given in the question because in several case you have to optimize your code and you can’t evaluate your code efficiency so it better to consider the constraints given in the question constraints is nothing but the inputs ranges present in the question

I have followed it…code was running successfully. Still it’s showing cases failed on submission.

@yutikakhanna hey yutika khanna share your code through cb.lk/ide of the coding blocks after pasting the code in this link and press the save button then it will generate a saved link that link you have to share.
