WebSep 27, 2024 · Binary Search Algorithm implemented in C++ In C++ the Standard Template Library (STL) provides the function lower_bound (), which can be used as shown in the following example [2]. There’s also the function binary_search (), which returns a boolean whether the target exists in the sorted array or not but not its position [1]. WebFind value in range Returns an iterator to the first element in the range [first,last) that compares equal to val. If no such element is found, the function returns last. The function uses operator== to compare the individual elements to val. The behavior of this function template is equivalent to: 1 2 3 4 5 6 7 8 9
