lower_bound() and upper_bound() in Vector of Pairs in C++

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. 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 returns an iterator pointing to that element, whereas upper_bound returns an iterator pointing to the next element.

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.
