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. WebJan 31, 2024 · Summary. We normally expect a binary search to have complexity of about O ( l o g N), and only descend to O ( N) in relatively rare worst cases. In this case, we get O ( N) in about the best case, and O ( N 2) in the bad cases. This violates the normal expectations of a binary search badly enough that it effectively only barely qualifies as a ... bioresorbable polymer scaffold
