Area not included in analysis.This function returns an iterator which points to the first element which is considered to go before the key k.
What is a map::lower_bound ()?3,4) returns an iterator pointing to the first element that compares not less (i.e.In michigan, 80% of voters say the economy is a top issue for them, followed by 77% of voters who say inflation is.
Map::lower_bound () function is an inbuilt function in c++ stl, which is defined in header file.Greater or equal) to the value x.
If the value exceeds the maximum value in map, then the iterator returned is equivalent to mapname.end().The c++ function std::map::lower_bound() returns an iterator pointing to the first element which is not less than key k.Lower_bound returns iterator pointing to the first element that is not less than key;
Otherwise the iterator is prev(s.lower_bound(x)).Once you grasp that, lower_bound returns the first starting iterator of equal_range and upper_bound returns the last one past the end ending iterator of equal_range.
With anything that can be compared to the key type, as long as the comparator explicitly opts in to this behavior.For arrays and vectors you can use the normal lower bound.C++98 iterator lower_bound (const key_type& k);
A similar answer for std::set is here.This overload participates in overload resolution only if the.
