Java Loops II

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

(a+2°. b), (a+2º .b+2¹.b),…, (a+2⁰.b+2¹.b+…+2^n-1.b)

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

Input Format

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

Constraints

• 0 ≤ q≤500
• 0 ≤ a, b ≤50
• 1 ≤ n ≤ 15

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 n 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 a=0 ,b=2 , and n=10 to produce some series S0, S1,…, Sn-1:
2. S0 = 0 + 1 * 2 = 2
3. S1 = 0 + 1 * 2 + 2 * 2 = 6
4. S2 = 0 + 1 * 2 + 2 * 2 + 4 * 2 = 14 … and so on.

Once we hit n=10 , we print the first ten terms as a single line of space-separated integers.

We use a=5,b=3 , and n=5 to produce some series S0,S1,……..,Sn-1:

1. S0 = 5+1*3 =8
2. S1 =5 +1*3 +2*3 =14
3. S2 = 5 + 1 * 3 + 2 * 3 + 4 * 3 = 26
4. S3 = 5 + 1 * 3 + 2 * 3 + 4 * 3 + 8 * 3 = 50
5. S4 = 5 + 1 * 3 + 2 * 3 + 4 * 3 + 8 * 3 + 16 * 3 = 98

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