 Java Loops II

We use the integers , , and  to create the following series:

You are given  queries in the form of , , and . For each query, print the series corresponding to the given , , and  values as a single line of  space-separated integers.

Input Format

The first line contains an integer, , denoting the number of queries.
Each line  of the  subsequent lines contains three space-separated integers describing the respective , , and  values for that query.

Constraints

Output Format

For each query, print the corresponding series on a new line. Each series must be printed in order as a single line of  space-separated integers.

Sample Input

2
0 2 10
5 3 5

Sample Output

2 6 14 30 62 126 254 510 1022 2046
8 14 26 50 98

Explanation

We have two queries:

1. We use , , and  to produce some series :

   ... and so on.

   Once we hit , we print the first ten terms as a single line of space-separated integers.

2. We use , , and  to produce some series :

   We then print each element of our series as a single line of space-separated values.

• Solution:

import java.util.*;

import java.io.*;

import java.lang.Math;

class Solution{

    public static void main(String []argh){

        Scanner in = new Scanner(System.in);

        int t=in.nextInt();

        for(int i=0;i<t;i++){

            int a = in.nextInt();

            int b = in.nextInt();

            int n = in.nextInt();

            int k=a;

            for(int j=0;j<n;j++){

                k+=(Math.pow(2,j)*b);

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

            }

            System.out.println();   

        }

        in.close();

    }

}
