The .NET framework includes various generic collections, such as Stack<T> for last-in-first-out operations, Queue<T> for first-in-first-out, List<T> for ordered and indexed elements, LinkedList<T> for doubly linked lists without indexing, and ISet<T> implementations lik...
A stack operates on the Last-In-First-Out (LIFO) principle, resembling a container where the most recently added element is the first to be removed. public class FixedSizeStack { private final int capacityLimit; private int topIndex; private final int[] storage; public FixedSizeStack(int limit) { th...
Problem Description We need to implement a stack that starts empty and supports four core operations: push x – Insert the number x at the top of the stack; pop – Remove the element from the top of the stack; empty – Check if the stack is empty; output "YES" if it is, otherwise "NO&quo...
