remove will remove all element equal to 3. beware, removing is not
erasing... Remove returns an iterator to the new end of the sequence s (it
does not actually modify s.end() ) , so you can use this iterator in the
vector::erase function. The size of the vector is not modified after a
remove, but the element between the returned end and the actual s.end() but
the element are unspecified.

so you can do

vector<int>::iterator NewEnd = remove(s.begin(), s.end(), 3);
s.erase(NewEnd, s.end);
