# Given three integers a, b, and n,output the following series: a+20b,a+20b+21b,……,a+20b+21b+…+2n−1ba+20b,a+20b+21b,……,a+20b+21b+…+2n−1b

Constraints:

• 0≤t≤500
• 0≤a,b≤50
• 1≤n≤15

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
```

This works in my IDE but when I try it in an online editor in hackerrank.com it throws an exception:

Exception in thread “main” java.util.NoSuchElementException: No line foundat java.util.Scanner.nextLine(Scanner.java:1585)at Solution.main(Solution.java:24)

Remove `iput.nextLine();` on line 24 so that no extra reading will happen.
