Java Loops II

    class Solution{ public static void main(String []argh){ Scanner in = new Scanner(System.in); int t=in.nextInt(); int v=0; for(int i=0;i 

        for(int k=0;k<n;k++)
    { for(int j=0;j<=k;j++)
        v=v+a+(b*(2^j));
       if(k!=n-1)
        System.out.print(v+" ");
        else{
            System.out.print(v);
        }
    }System.out.println("\n");
    v=0;
    }
    in.close();
}

    }

    //can you help me where i went wrong

      you can not use ^ in java (i guess in programming ) use Math.pow(arg1,arg2) check this for more detail

      check my code @ https://codeshare.io/arJ93q ask me if any issue or you can inhence my code -thank you

        You can use the '^' in programming. Python, Pearl, (not sure if on Ruby is possible) are some languages that support the use of '^'.

        yes, instead of this use Math.pow() operator..... Hope this is helpful!!!!

        for(int i=0;i 

                int sum = a+b;
        for(int j=1; j<=n; j++){
            System.out.print(sum+" ");
            sum+=((Math.pow(2,j))*b);
        }
        System.out.println();
    }

          smart and excellent

          for Math.pow j has to be double, it won't work

          • rr_theprogrammer + 0 comments
            use type cast  (int)
        • sjsouvik + 0 comments

          use type cast int as pow returns double and this code won't pass all the testcases. You need to use long to pass all the testcases

          fabulous

      and also you have to display the answer in two lines you cannot enter the next line such as if you have two different set of values as answer you have to display them in two lines but with your program after that you are entering the third line

      you cant use to the power here(2^j) you have to use math.pow() function

    • Aarkay360 + 0 comments

      that a is added n times in last term of series and n-1 times in second last term of series and n-2 times in third last term of series ...... ..... ..... and a is added only once in each term of series. So u can print System.out.println(v+a); instead of adding the a in each term.

      println itself means a new line so make it like

      System.out.println();
