Jan 17, 2023 · upper_bound () is a standard library function in C++ defined in the header . It returns an iterator pointing to the first element in the range [first, last] that is greater than value, or last if no such element is found.
May 20, 2024 · Returns the first iterator iter in [first,last) where bool(comp(value, *iter)) is true, or last if no such iter exists. If the elements elem of [first,last) are not partitioned with respect to the expression bool(comp(value, elem)), the behavior is undefined.
<algorithm> std:: upper_bound. Return iterator to upper bound. Returns an iterator pointing to the first element in the range [first,last) which compares greater than val. The elements are compared using operator< for the first version, and comp for the second.
Jan 31, 2017 · The simple answer is [ lower_bound, upper_bound ) s.lower_bound(t) will return iterator to the first element v in set such that v >= t s.upper_bound(t) will return iterator to the first element v in set such that v > t. When we often call xxxxx_bound for the STL set or map, we often want to find the data in some range.
ForwardIt upper_bound ( ForwardIt first, ForwardIt last, const T & value, Compare comp ); Returns an iterator pointing to the first element in the range [ first; last) such that value < element (or comp(value, element)) is true (i.e. that is strictly greater than value), or last if no such element is found.
ForwardIt upper_bound (ForwardIt first, ForwardIt last, const T & value, Compare comp ); (2) Returns an iterator pointing to the first element in the range [first, last) that is greater than value .
std:: upper_bound. C++. Algorithm library. Returns an iterator pointing to the first element in the range [first, last) that is greater than value, or last if no such element is found.
Nov 29, 2021 · std::map<Key,T,Compare,Allocator>:: upper_bound. 1,2) Returns an iterator pointing to the first element that is greater than key. 3,4) Returns an iterator pointing to the first element that compares greater to the value x. This overload participates in overload resolution only if the qualified-id Compare::is_transparent is valid and denotes a type.
The upper_bound() algorithm searches the ordered range [start,end) for the last location that val could be inserted without disrupting the order of the range. If the strict weak ordering function object cmp is given, it is used to compare elements instead of the < operator.
Dec 30, 2019 · Here we will see that is the upper_bound() function in C++ STL. This function returns an iterator that points to the first element in the container, which is considered to go after val. The syntax is like: iterator upper_bound (const value_type& val); const_iterator upper_bound (const value_type& val) const;
