Question 1

WAP to input a number n and print the following pattern uptil n lines

1
11
111
1111
11111
111111
In this example n = 6

java 

        
            
import java.util.*;
public class Test
{
public static void main()
{
    int i, j, n;
    Scanner sc = new Scanner(System.in);
    
    System.out.println("enter the number of lines");
    n = sc.nextInt();
    
    for (i = 1; i<= n; i++)
    {
        for (j = 1; j <= i; j++)
            System.out.print("1");
        System.out.println();
    }
}
}

python 

        
            
n = int(input("Enter the number of lines: "))

for i in range(1, n + 1, 1):
    for j in range(1, i + 1, 1):

{
    int i, j, n;
    Scanner sc = new Scanner(System.in);
    
    System.out.println("enter the first number");
    n = sc.nextInt();
    
    for (i = 1; i<= n; i++)
    {
        for (j = 1; j <= i; j++)
