       System.out.println("Enter the number of iterations needed");

       int n = sc.nextInt();

       int sum = 0;

       

       //using for loop

       for(int i=1;i<=n;i++){

           sum += 4*i;

       }

       

       //using while loop

       int i = 1;

       while(i<=n){

           sum += 4*i;

           i++;

       }
