1 2 3 4​

Answer 1

Answer:

//Assuming it is Java programming

class Abc{

public static void main (String ar[]){

for(int I=1;I<=4;I++){

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

System.out.println(j+" ");

System.out.println();

}

}

}

Logic:-

• Run I loop from 1 to 4
• Run j loop from 1 to I
• print j loop
• close j loop
• Use System.out.println() to bring the cursor to next line
• Close I loop
• close the main () and the class
