How to implement the Stack using a Single Queue? The Stack can be easily implemented by making the insertion operation costly. For the push operation i.e. the insertion operation, we will store the count of the elements (n) present in the stack. Then, the new element is inserted at the...
// Return whether the queue is empty. publicbooleanempty() { returnstack.isEmpty(); } }
how you could implement this ADT by using existing Java ADTs as building blocks. What’s the most efficient implementation you can come up with? importjava.util.Comparator;importjava.util.PriorityQueue;publicclassMedianFinder {privatePriorityQueue<Integer>smallerHalf;privatePriorityQueue<Integer>largerHalf;...
tail_(head_.load()) {} ~LockFreeQueue() { while (Node* old_head = head_.load()) { head_.store(old_head->next); delete old_head; } } LockFreeQueue(const LockFreeQueue& other) = delete; LockFreeQueue& operator=(const LockFree...
Another important aspect to consider when dealing with the queue stack problem is the time and space complexity of the implemented solution. It is crucial to analyze the efficiency of the implementation in terms of the time taken to perform enqueue and dequeue operations, as well as the space ...
The most common stack implementation is using arrays, but it can also be implemented using lists. Python Java C C++ # Stack implementation in python # Creating a stack def create_stack(): stack = [] return stack # Creating an empty stack def check_empty(stack): return len(stack) == 0...
typically, you can only view the top element of a stack, which is the last item that was added. however, depending on the implementation and the language, there may be ways to view all the elements in the stack using debugging tools or by converting the stack to another data structure. ...

OK, I am quite sure that the OP's implementation is correct. @rolfl was marked as the correct answer is not right. MyQueue<String> q = new MyQueue<>(); q.add("a"); q.add("b"); q.remove(); // should be "a", and is "a". q.add("c"); q.remove(); // should ...
