Lecture 81:- Demo - Increasing Array Size

Here's a demo that showcases how to increase the size of an array or a dynamic array in different programming languages:

Python:

pythonCopy code

# Create a list my_list = [1, 2, 3] # Increase the size by appending elements my_list.append(4) my_list.append(5) print(my_list)  # Output: [1, 2, 3, 4, 5]

JavaScript:

javascriptCopy code

// Create an array let myArray = [1, 2, 3]; // Increase the size by pushing elements myArray.push(4); myArray.push(5); console.log(myArray);  // Output: [1, 2, 3, 4, 5]

Java:

javaCopy code

import java.util.ArrayList; public class ArrayResizeDemo {    public static void main(String[] args) {        // Create an ArrayList        ArrayList<Integer> myArrayList = new ArrayList<>();        // Increase the size by adding elements        myArrayList.add(1);        myArrayList.add(2);        myArrayList.add(3);        System.out.println(myArrayList);  // Output: [1, 2, 3]    } }

In all the examples:

1. We start with an initial array or dynamic array containing a few elements.
2. We increase the size by appending or pushing additional elements to the end of the array or dynamic array.
3. Finally, we print the updated array or dynamic array to verify the size increase.

Output:

makefileCopy code

Python: [1, 2, 3, 4, 5] JavaScript: [1, 2, 3, 4, 5] Java: [1, 2, 3]

As shown in the output, the size of the array or dynamic array is increased by adding elements to the end. The examples demonstrate how the size of the array or dynamic array can be expanded dynamically in different programming languages.
