Using extra stuff!?

#1

I used str.startsWith() here, how are we supposed to do this question without it , as this was not covered in the lecture??
or using this is fine?

#2

Also in the editorial the solutions are mentioned only in c++, please include them in java too

@bhavik911,

You need to define your own comparator for this problem.

Compare the characters one by one and make sure that i < s1.length() && i < s2.length(). If there exists a prefix, the next ’ if ’ condition will take care of it.
