How do I merge and splice sequences with std::queue?

In C++, merging and splicing sequences can be effectively managed using the `std::queue` container. Although `std::queue` does not provide direct merging operations like some other data structures, we can achieve the desired outcome through manipulation of the queue elements. Below is an example to demonstrate how to merge two queues into one.

#include #include void mergeQueues(std::queue& q1, std::queue& q2) { // Move all elements from q2 to q1 while (!q2.empty()) { q1.push(q2.front()); q2.pop(); } } int main() { std::queue queue1; std::queue queue2; // Populate queue1 queue1.push(1); queue1.push(2); queue1.push(3); // Populate queue2 queue2.push(4); queue2.push(5); queue2.push(6); // Merging queue2 into queue1 mergeQueues(queue1, queue2); // Display merged queue while (!queue1.empty()) { std::cout << queue1.front() << " "; queue1.pop(); } return 0; }
