The main stack operations are: push (int data):Insertion at top int pop():Deletion from top Implementing Queue using stack A queue can be implanted using stack also. We need two stacks for implementation. The basic idea behind the implementation is to implement the queue operations (enqueue,...
We will implement same behavior using Array. Although java provides implementation for all abstract data types such as Stack, Queue and LinkedList but it is always good idea to understand basic data structures and implement them yourself. Please note that Array implementation of Queue is not ...
The complexity of enqueue and dequeue operations in a queue using an array isO(1). If you usepop(N)in python code, then the complexity might beO(n)depending on the position of the item to be popped. Applications of Queue CPU scheduling, Disk Scheduling ...
bool isEmpty():returns true if stack is empty, else returns false bool isFull():returns true if stack is full, else returns false int size():Returns size of the stack Example: Let the elements inserted are 1, 2, 3, 4 Stack Implementation using Array In C++ ...
username,"/queue/greetings","Hello "+ username); Let’s now look at how to implement a JavaScript (SockJS) client capable of receiving private messages which could be sent by the Java code in the example above. It is worth knowing that WebSockets are a part of HTML5 specification and ar...
1. How would you implement a stack in C using an array? Here is an example implementation of a stack using an array in C : #define MAX_SIZE 100 int stack[MAX_SIZE]; int top = -1; void push(int item) { if (top == MAX_SIZE - 1) { printf("Stack Overflow"); return; } top...
We can implement a stack in any programming language like C, C++, Java, Python or C#, but the specification is pretty much the same. Basic Operations of Stack There are some basic operations that allow us to perform different actions on a stack. Push: Add an element to the top of a ...
