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

In C++, performing a binary search on a `std::forward_list` is not directly possible as `std::forward_list` is not a random-access container, which is a requirement for binary search algorithms. However, you can convert the `std::forward_list` to a vector or an array and then perform a binary search on that. Below is an example demonstrating how to do this.

#include #include #include #include int main() { std::forward_list fl = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; // Converting forward_list to a vector std::vector vec(fl.begin(), fl.end()); // Value to search in the vector int valueToSearch = 5; // Performing binary search bool found = std::binary_search(vec.begin(), vec.end(), valueToSearch); if (found) { std::cout << "Value " << valueToSearch << " found in the forward_list." << std::endl; } else { std::cout << "Value " << valueToSearch << " not found in the forward_list." << std::endl; } return 0; }
