Binary search is one of the most popular algorithms which searches a key from a sorted range in logarithmic time complexity. First, we need a sorted range for the binary search to work. Binary search can't work

binary_search (STL/CLR) 測試已排序的序列是否包含指定的值。 copy (STL/CLR) 將值從來源範圍複製到目的地範圍,朝正向反覆運算。 copy_backward (STL/CLR) 將值從來源範圍複製到目的地範圍,以向後方向反覆運算。 count (STL/CLR) 傳回範圍中值符合指定值的項目數目。 count_if (STL/CLR) 傳回範圍中值符合...
