Lower bound and upper bound of C++ by Jimmy (xiaoke) Shen

WebA similar member function, upper_bound, has the same behavior as lower_bound, except in the case that the multiset contains elements equivalent to val: In this case lower_bound returns an iterator pointing to the first of such elements, whereas upper_bound returns an iterator pointing to the element following the last. Parameters val WebFirst we specify the case (worst,best, average, etc.) and then we specify O, Ω (upper bound, lower bound) or Θ (tight bounds). For Binary search: In the best case scenario (our initial guess finds the target value): - binary search is Θ (1) and as a result is also Ω (1) and O (1). In the worst case scenario (our target is not in the array) st gabriel band club balzan

Webset::lower_bound takes advantage of knowing it's applying this operation on a set and it's properties. Ensuring logN time. While std::lower_bound only promises logN time if the iterators are random. Set iterator is a not a random one ( as far as I know, I don't mainly use C++), so that explains the time.
