Stacks and queues are data structures used to store and manipulate collections of elements.
Stacks follow the Last-In-First-Out (LIFO) principle, where the last element added is the first one to be removed.
Queues follow the First-In-First-Out (FIFO) principle, where the first element added is the first one to be removed.
Examples of stacks include the call stack in programming and the undo/redo feature in text editors.
Ex...
Yes, we can implement queues using two stacks.
We can use two stacks, one for enqueue operation and another for dequeue operation.
To enqueue an element, push it onto the first stack.
To dequeue an element, pop all elements from the first stack and push them onto the second stack, then pop the top element from the second stack.
This ensures that the first element that was enqueued is the first one to be dequeued.
Time compl...
Yes, we can implement circular queues using two stacks.
We can use two stacks to implement a circular queue.
One stack will be used for enqueue operation and the other for dequeue operation.
When the enqueue stack is full, we can transfer all elements to the dequeue stack and vice versa.
This way, we can maintain the circular nature of the queue.
Example: https://www.geeksforgeeks.org/queue-using-stacks/
Heap sort is a comparison-based sorting algorithm that uses a binary heap data structure.
It divides the input into a sorted and an unsorted region.
It repeatedly extracts the maximum element from the unsorted region and inserts it into the sorted region.
It has a worst-case time complexity of O(n log n).
Yes, I know other sorting algorithms.
Examples: Merge Sort, Quick Sort, Heap Sort, Bubble Sort, Insertion Sort, Selection Sort
Each algorithm has its own advantages and disadvantages.
The choice of algorithm depends on the size of the data set and the desired time complexity.

One stack is used for enqueue operation and the other for dequeue operation.

This ensures that the ...
Yes, circular queues can be implemented using two stacks.
Use two stacks, one for enqueue and one for dequeue operations.
When enqueueing, push the element onto the enqueue stack.
When dequeuing, if the dequeue stack is empty, pop all elements from the enqueue stack and push onto the dequeue stack.
The front of the queue is the top element of the dequeue stack.
When dequeueing, pop the top element from the dequeue stack.

Yes, I know several sorting algorithms.
One of the most popular is QuickSort, which uses a pivot element to divide the array into smaller sub-arrays and recursively sorts them.
Another common algorithm is MergeSort, which divides the array into smaller sub-arrays and then merges them back together in sorted order.
InsertionSort is a simple algorithm that iterates through the array and inserts each element into its correct...
