This is implemented by a modified queue called the circular queue. Complexity Analysis 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 ...

Queue Implementation using Two Stacks in C++: Here, we are going to implement a C++ program to implement Queue using two Stacks.
DequeueOperation, die ein Element von der vorderen Position in der Queue entfernt. Peekoderfront-Operation, die das vordere Element zurückgibt, ohne es aus der Queue zu nehmen oder die Queue in irgendeiner Weise zu ändern. Die Queue wird auch als First-In, First-Out (FIFO)-Datenstruktur...
I implemented two versions of a Fibonacci heap one using a unordered map (mapping keys to their nodes) so that the client can call decrease in O(1)O(1) average and amortized time. The other one with a dynamic array of nodes and a maximum size for the same reason but in O(1)O(1...
fstrmis an optimized C implementation of Frame Streams that includes a fast, lockless circular queue implementation and exposes library interfaces for setting up a dedicated Frame Streams I/O thread and asynchronously submitting data frames for transport from worker threads. It was originally written to...
queue.remove();// removing the front element (`A`) queue.remove();// removing the front element (`B`) // Prints the front of the queue (`C`) System.out.println("The front element is "+queue.peek()); // Returns the total number of elements present in the queue ...

In C++, the string can be represented as an array of characters or using string class that is supported by C++. Each string or array element is terminated by a null character. Representing strings using a character array is directly taken from the ‘C’ language as there is no string type...
