  We use the integers a, b, and n to create the following series:
  
  (a + 2^0.b), (a + 2^0.b + 2^1.b), ... , (a + 2^0.b + 2^1.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 a_i, b_i, and n_i values for that query. 
  
  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
