so i was solving a cses question and i had a confusion...why dont we sort a set or multiset before applying lower bound and upper bound? i saw some solutions and they just simply added the elements and directly applied lower bound and upper bound.

It's because they are sorted data structures. You might want to read the references for these containers on Cppreference.
Sorted data structures = Already sorted right? also why do they have a separate lower bound and upper bound function. why not use the std:lowerbound and upperbound?
Oh, so you were asking for why they had their own member function. You can refer to the functions' reference for this, see the reference for std::lower_bound, especially the section labeled Complexity.
