C set lower_bound
WebJan 4, 2024 · Here are two methods that take an already-sorted vector, and insert a single item into the vector, maintaining the sorted property of the vector (i.e. after calling this method, calling std::is_sorted on the vector will still return true). This first method uses the naive approach of appending + sorting, the second method uses std::upper_bound ... Webupper_bound () is an inbuilt function in C++. It is used to return an iterator pointer to the key (parameter) from the set. This function is applied to an ordered set. It takes a parameter and returned a value next (greater one) to the equivalent value to the passed parameter. And if there is no value greater than the passed value in the set ...

Lower bound of x means the first number in the set that's not considered to go before x. So, if x is itself present, then it's x else immediate next of x. … Webpair will compare the first int first, then the second int. We want ALL second integers to work. As for upperbound Na2a uses {first, inf} because we want the value to be greater than first, and {first, inf} is the highest pair with first as its first value.
