C++ set pair lower_bound
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.
