What is the runtime complexity of the Dijkstra algorithm?
The runtime complexity of the Dijkstra algorithm is O(V2) with a simple implementation using an adjacency matrix, or O(E V log V) with a more efficient implementation using a priority queue.
What is the runtime of Prim's algorithm for finding the minimum spanning tree of a graph?
The runtime of Prim's algorithm for finding the minimum spanning tree of a graph is O(V2) with a simple implementation, or O(E log V) with a more efficient implementation using a priority queue.
How can you implement a queue using stacks efficiently?
To implement a queue using stacks efficiently, you can use two stacks. One stack is used for enqueueing elements, and the other stack is used for dequeueing elements. When dequeueing, if the dequeue stack is empty, you can transfer elements from the enqueue stack to the dequeue stack to maintain the order of elements. This approach allows for efficient implementation of a queue using stacks.
What is the runtime of Dijkstra's algorithm for finding the shortest path in a graph?
The runtime of Dijkstra's algorithm for finding the shortest path in a graph is O(V2) with a simple implementation using an adjacency matrix, or O((V E) log V) with a more efficient implementation using a priority queue.
What is the running time of the Dijkstra algorithm for finding the shortest path in a graph?

Write a program in c language to reverse elements of a queue?
There are many ways to reverse the order of the elements in a queue. Provided that you have access to the implementation of the queue, it is of course easy to read the elements from the tail end rather than the front end, thus reversing the elements. However, considering the queue as a black box, and assuming the queue only allows for its characteristic operations (removal of head element, addition to tail), the best method to reverse the elements in a queue to engage a stack. You'd remove the elements from the queue (always reading the head of the queue), and push each element onto the stack. When the queue is empty, you reverse that process: pop each element from the stack until it is empty, and add each element in this order to the end of the queue. Your queue will have the exact same elements as in the beginning, but in reverse order. The exact implementation of this in C, or in any other programming language, is trivial, but the exact source code depends on the implementation of queue and stack containers. Following is pseudocode: Queue<Item> reverse (Queue<Item> queue) { Stack<Item> stack; Item item; while (queue.remove(&item)) { stack.push(item); } while(stack.pop(&item)) { queue.add(item); } return queue; }
What is the runtime complexity of the Dijkstra algorithm?

Circular queue in linear data structure?
The queue is a linear data structure where operations of insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. A circular queue is similar to the normal queue with the difference that queue is circular queue ; that is pointer rear can point to beginning of the queue when it reaches at the end of the queue. Advantage of this type of queue is that empty location let due to deletion of elements using front pointer can again be filled using rear pointer.
What ios meant by queue implementation?
In computer science, a queue is a particular kind of abstract data type or collection in which the entities in the collection are kept in order and the principal (or only) operations on the collection are the addition of entities to the rear terminal position, known as enqueue, and removal of entities.
What is the runtime of Prim's algorithm for finding the minimum spanning tree of a graph?
