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.
2. Once we hit , we print the first ten terms as a single line of space-separated integers.
3. We use , , and  to produce some series :
   •  
   •  
   •  
   •  
   •  
   We then print each element of our series as a single line of space-separated values.
