Introduction to Extract Stack

Extract Stack is a powerful tool that offers developers a wide range of APIs to interact with, handle, and manipulate stacks of data efficiently. In this article, we will explore these APIs with code snippets and a comprehensive application example that integrates various APIs discussed.

Core API Methods

CreateStack

Initialize a new stack data structure.

  
    const stack = CreateStack();
  

Push

Adds an element to the top of the stack.

  
    stack.Push(10);
    stack.Push(20);
  

Pop

Removes the top element from the stack and returns it.

  
    let topElement = stack.Pop();
  

Peek

Returns the top element of the stack without removing it.

  
    let topElement = stack.Peek();
  

IsEmpty

Checks if the stack is empty and returns a boolean value.

  
    let checkEmpty = stack.IsEmpty();
  

Size

Returns the number of elements in the stack.

  
    let stackSize = stack.Size();
  

Application Example

Here is an example application using the Extract Stack APIs to manage a stack of numbers:

  
    // Initialize a new stack
    const stack = CreateStack();

    // Push elements to the stack
    stack.Push(10);
    stack.Push(20);
    stack.Push(30);

    // Peek the top element
    console.log('Top element:', stack.Peek()); // Output: Top element: 30

    // Pop the top element
    console.log('Removed element:', stack.Pop()); // Output: Removed element: 30

    // Size of the stack after popping
    console.log('Current stack size:', stack.Size()); // Output: Current stack size: 2

    // Check if the stack is empty
    console.log('Is stack empty:', stack.IsEmpty()); // Output: Is stack empty: false
  

As seen in the above example, the Extract Stack API provides a convenient way to manage and interact with stack data structures, making it an essential tool for developers.
