WebJan 10, 2024 · std::set:: insert. Inserts element (s) into the container, if the container doesn't already contain an element with an equivalent key. 1-2) inserts value. 3-4) inserts value in the position as close as possible to the position just prior to pos. 5) Inserts elements from range [first, last). WebApr 17, 2024 · standard-template-library. anon13516274 April 17, 2024, 8:06pm #1. in this code, as you see in this picture link I made a custom comparator for lower_bound () so it supposes to 100 as output in the end as in the lst compare 100 <=100 is true but it gives the next index 200 as output why? please explain thank you. ssjgz April 17, 2024, 9:43pm #2.

WebA similar member function, upper_bound, has the same behavior as lower_bound, except in the case that the set contains an element equivalent to val: In this case lower_bound … WebA similar member function, upper_bound, has the same behavior as lower_bound, except in the case that the map contains an element with a key equivalent to k: In this case, lower_bound returns an iterator pointing to that element, whereas upper_bound returns an iterator pointing to the next element. Parameters k Key to search for. WebThe function lower_bound () finds the position of the pair equal or greater than the pair searched for. So, if one is found in the vector it is allways true that: the string part is bigger or equal. in case the string part is equal the int part is bigger or equal. The int part of the pair is used in comparison whenever the string part is equal. howdens isle of man
