Answer 1

Answer:

This is done in JAVA

Code:-

int i,s=1;

for (I=1;I<=5;I++)

{

System.out.print(s+",");

s=s*10+1;

}

Output:-

1,11,111,1111,11111

Answer 2

Question:-

➡ Write a program to display the following series.

1 11 111 1111 11111

Program:-

This can be solved using 2 ways.

1. Using 1 loop.
2. Without using loop.

Using 1 loop

import java.util.*;

class Series

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.print("Enter the value of n: ");

int n=sc.nextInt();

int a=1;

for(int i=1;i<=n;i++, a=a*10+1)

System.out.print(a+" ");

}

}

Without using loop.

import java.util.*;

class Series

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.print("Enter the value of n: ");

int n=sc.nextInt();

printPattern(1,n,1);

}

static void printPattern(int initial, int final, int a)

{

if(initial<=final)

{

System.out.print(a+" ");

a=a*10+1;

printPattern(++initial, final, a);

}

}

}
