I think the question in the below link is not complete.

please guide me if I am wrong.

Why do you think the question is incomplete?

no input instruction for â€śNâ€ť is mentionedâ€¦without â€śNâ€ť we cannot determine the length of the individual square shaped kerchief.

With 3500+ correct submissions, you can hardly tout this question as incomplete. Since N is not given, you can assume that you are free to choose whatever youâ€™d like, but the question specifies that you need to split it such that S is maximized. From the question, one can see that youâ€™ll need to minimize N as much as possible to get the maximum S required.
