Question

1
12
123

Answer 1

Answer:

public class Pattern

public class Pattern{

public class Pattern{public static void main(String args[])

public class Pattern{public static void main(String args[]){

public class Pattern{public static void main(String args[]){int a,b;

public class Pattern{public static void main(String args[]){int a,b;for(a=1;a<=3;a++)

public class Pattern{public static void main(String args[]){int a,b;for(a=1;a<=3;a++){

public class Pattern{public static void main(String args[]){int a,b;for(a=1;a<=3;a++){for(b=1;b<=a;b++)

public class Pattern{public static void main(String args[]){int a,b;for(a=1;a<=3;a++){for(b=1;b<=a;b++){

public class Pattern{public static void main(String args[]){int a,b;for(a=1;a<=3;a++){for(b=1;b<=a;b++){System.out.print(b);

public class Pattern{public static void main(String args[]){int a,b;for(a=1;a<=3;a++){for(b=1;b<=a;b++){System.out.print(b);}

public class Pattern{public static void main(String args[]){int a,b;for(a=1;a<=3;a++){for(b=1;b<=a;b++){System.out.print(b);}System.out.println("");

public class Pattern{public static void main(String args[]){int a,b;for(a=1;a<=3;a++){for(b=1;b<=a;b++){System.out.print(b);}System.out.println("");}

public class Pattern{public static void main(String args[]){int a,b;for(a=1;a<=3;a++){for(b=1;b<=a;b++){System.out.print(b);}System.out.println("");}}

public class Pattern{public static void main(String args[]){int a,b;for(a=1;a<=3;a++){for(b=1;b<=a;b++){System.out.print(b);}System.out.println("");}}}

Hope this mark as brainliest.

Answer 2

Given pattern:-

1

12

123

Hint:-

• Each row increases numerically by 1
• The last elements of each row also increases numerically by 1
• It means outer loop will run from 1 to 3(or no. of lines of the pattern)
• inner loop will run from 1 to outer loop value

Approach

class patt{

public static void main (String ar []){

for(int I=1;I<=3;I++){

for(int j=1;j<=I;j++)

System.out.print(j);

System.out.ptintln();

}

}

}

Note:-

• For n no. of lines simply change condition in outer loop from I<=3 to I<=n taking no. of lines as input .
