Difference between DFS and BFS?
1. bfs uses queue implementation ie.FIFO dfs uses stack implementation ie. LIFO 2. dfs is faster than bfs 3. dfs requires less memory than bfs 4. dfs are used to perform recursive procedures.
How many cards are in a stack?
There is exactly 52 cards in a normal stack.
Is stack an abstract noun or concrete noun?
The noun 'stack' is a concrete noun; a word for a pile of objects; a word for a chimney or a vertical exhaust pipe on a vehicle; a word for a physical thing.The word 'stack' is also a verb: stack, stacks, stacking, stacked.

How many cubes would you need to build a stack that was 3 cubes long 2 cubes high and 4 cubes deep?
Well, isn't that just a delightful little stack of cubes you're imagining! To build a stack that is 3 cubes long, 2 cubes high, and 4 cubes deep, you would need a total of 24 cubes. Just imagine all the happy little details you could add to each cube as you stack them up!
What is difference between stack snd queue?
In stack , the object which is last in will be first out (LIFO), whereas in queue the object which is first in will be first out (FIFO).
What difference between stack and queue?
A stack is a data structure in which last item inserted is taken out first . That's why they are known as LIFO (last in first out). Inserting an item in stack is termed as push and taking an item out from stack I s termed as pop. Some applications of stack are : Polish notation, reversing string, backtracking , quick sort algorithm etc. The queue is a linear data structure where operations od 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. Whenever a new item is added to queue, rear pointer is used. and the front pointer is used when an item is deleted from the queue.
What is the difference between a queue and a stack with example?
A stack is a data structure in which last item inserted is taken out first . That's why they are known as LIFO (last in first out). Inserting an item in stack is termed as push and taking an item out from stack I s termed as pop. Stack pointer is the pointer that points to the top of the stack or that points the item at the top of the stack and help in adding or deleting the item from the top of stack. 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. types of queues : circular, linear, double ended and priority
Difference between a queue and a stack in brief?
In a queue, elements are placed in line; the first to get into the queue is the first to get out (FIFO - first in, first out).A stack is also a structure to store pieces of data, or objects, but the last element to get in will be the first element to get out (LIFO).In a queue, elements are placed in line; the first to get into the queue is the first to get out (FIFO - first in, first out).A stack is also a structure to store pieces of data, or objects, but the last element to get in will be the first element to get out (LIFO).In a queue, elements are placed in line; the first to get into the queue is the first to get out (FIFO - first in, first out).A stack is also a structure to store pieces of data, or objects, but the last element to get in will be the first element to get out (LIFO).In a queue, elements are placed in line; the first to get into the queue is the first to get out (FIFO - first in, first out).A stack is also a structure to store pieces of data, or objects, but the last element to get in will be the first element to get out (LIFO).
Why does LIFO order follows in stack and why does FIFO order follows in queue?
LIFO and stack are synonyms, so are FIFO and queue.
What are the different between stack and queue?
A stack is generally First In, Last Out, and a queue is First In First Out.Item can be added or removed only at one end in stack and in a queue insertion at the rear and deletion from the front.The basic operation of stack are 'push' and 'pop', on other hand of queue are 'enque' and 'dequeue'.
Is cursor implementation possible in queue or stack?
yes,cursor implementation possible in priority queue.
Double ended stack?
Double ended queue
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; }
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 to Compare and contrast between stack and queue?
A stack is a data structure in which last item inserted is taken out first . That's why they are known as LIFO (last in first out). Inserting an item in stack is termed as push and taking an item out from stack I s termed as pop. Some applications of stack are : Polish notation, reversing string, backtracking , quick sort algorithm etc. The queue is a linear data structure where operations od 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. Whenever a new item is added to queue, rear pointer is used. and the front pointer is used when an item is deleted from the queue.
