How do I binary search with algorithms with std::array?

Binary search is an efficient algorithm for finding an element from a sorted array. In C++, we can utilize the `std::array` container for this purpose. Below is an example of how to perform a binary search using algorithms in C++ with `std::array`.

#include <iostream> #include <array> #include <algorithm> int main() { std::array arr = {1, 2, 3, 4, 5, 6}; int target = 4; auto result = std::lower_bound(arr.begin(), arr.end(), target); if (result != arr.end() && *result == target) { std::cout << "Element found at index: " << std::distance(arr.begin(), result) << std::endl; } else { std::cout << "Element not found." << std::endl; } return 0; }
