Binary search using c++
WebJul 2, 2024 · Both methods take a range [start, end) with n elements and and a value x that is to be found as input. But note the important difference that std::binary_search only returns a bool that tells you wether the range contained the element, or not. std::find () returns an iterator. So both have different, but overlapping use cases. WebJun 18, 2024 · This technique is a simple modification in the binary search when MID is calculated. Mid = low + (high – low) * ( (item – LIST [low]) / (LIST [high] – LIST [low])); Advantages If the items are uniformly distributed, the average case time complexity is log 2 (log 2 (n)). It is considered an improvement in binary search. Disadvantages
