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

Binary searching in a queue is not directly possible, because a queue is a first-in-first-out (FIFO) data structure. However, you can convert the queue to a data structure that supports binary search, such as a vector or array. Below is an example demonstrating how to achieve this.

#include #include #include #include int main() { // Create a std::queue and populate with sorted elements std::queue q; for (int i = 0; i < 10; ++i) { q.push(i); // Adding elements 0 to 9 } // Convert the queue to a vector std::vector vec; while (!q.empty()) { vec.push_back(q.front()); q.pop(); } // Now perform binary search on the vector int target = 5; bool found = std::binary_search(vec.begin(), vec.end(), target); if (found) { std::cout << "Element " << target << " found in the queue." << std::endl; } else { std::cout << "Element " << target << " not found in the queue." << std::endl; } return 0; }
