Java Code :-

import java.util.Scanner;
public class MainClass
{
    public static void main(String[] args)
    {
        Scanner sc = new Scanner(System.in);
        
        //Taking rows value from the user
        
        System.out.println("How Many Rows Do You Want In This Pattern ?");
        
        int rows = sc.nextInt();
        
        System.out.println("Here's your pattern !");
        
        for (int i = 1; i <= rows; i++)
        {
            for (int j = 1; j <= i; j++)
            {
                System.out.print(j+" ");
            }
            
            System.out.println();
        }
        
        //Close the resources
        
        sc.close();
    }
}
