/*

In this problem you will test your knowledge of Java loops. Given three integers aa, bb, and nn, output the following series:

a+20b,a+20b+21b,......,a+20b+21b+...+2n−1ba+20b,a+20b+21b,......,a+20b+21b+...+2n−1b

Input Format

The first line will contain the number of testcases t. Each of the next tt lines will have three integers, aa, bb, and nn.

Constraints:

0≤t≤5000≤t≤500

0≤a,b≤500≤a,b≤50

1≤n≤151≤n≤15

Output Format

Print the answer to each test case in separate lines.

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
