In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array. If they are not equal, the half in which the target cannot lie is eliminated and the search continues on the remaining half constexprbool binary_search ( ForwardIt first, ForwardIt last, const T& value, Compare comp ); (since C++20) Checks if an element equivalent to value appears within the partitioned range [first,last) . 1) The equivalence is checked using operator< : If bool(*iter < value)&&!bool(value <*iter) is true for some iterator iter in [first,last Binary Search. Binary search is an efficient algorithm that searches a sorted list for a desired, or target, element. For example, given a sorted list of test scores, if a teacher wants to determine if anyone in the class scored \ (80\), she could perform a binary search on the list to find an answer quickly. Binary search works by halving the 二分探索法 (バイナリサーチ)とは？. あらかじめソートされた配列を前半と後半に区切る処理を繰り返すことで探索範囲を狭め、. 目的の結果にたどり着くアルゴリズムです. 配列のインデックス（最初・最後）を元に割り出した. 真ん中の配列の中身の数値 Binary search is a search algorithm that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array. The course was developed by Harsha and Animesh from MyCodeSchool.
