Algorithm for the Implementation of Queue using Array For Insertion: Step 1: Get the position of the first empty space ( value of the rear variable) Step 2: Assign the new value to position the rear in an array if the queue is not full. Step 3: Increment the value of the rear variab...
A Queue can be implemented in many ways using arrays,linked lists, Pointers and Structures. But for some simplicity’s sake, we should implement it using the single-dimensional or one-dimensional array. Before going into detail, we should have prior knowledge of when to use the current data ...
const int increased_count = old_node->external_count - 2; NodeCounter old_counter = ptr->counter.load(); NodeCounter new_counter; // Update two counters using a single compare_exchange_strong() on the // whole count structure, as we did when decreasing the internal_count // in Release...
Dequeue:Dequeue is known as double ended queue. In dequeue, the elements can be inserted or removed from both of the ends. Due to this property, dequeue may not follow the first in first out property. Queue implementation using Array: For the implementation of queue, we need to initialize ...
Size:Returns the total number of elements present in the queue. Practice this problem Queue Implementation using an array: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33
However, using std::queue, I couldn't separate the two. Maybe that is why the other author used an looping array instead? Here is my second attempt: #include <iostream> #include <mutex> #include <condition_variable> #include <thread> template <typename T> class OneToOneBlockingQueue...
The complexity of enqueue and dequeue operations in a queue using an array is O(1). If you use pop(N) in python code, then the complexity might be O(n) depending on the position of the item to be popped. Applications of Queue CPU scheduling, Disk Scheduling When data is transferred ...

Queue Implementation using Two Stacks in C++: Here, we are going to implement a C++ program to implement Queue using two Stacks.
