Geometric Sequence Generator

You are given three integers a, r, and n representing the first term, the common ratio, and the number of terms of a geometric sequence respectively. The geometric sequence is defined by the formula:

$$a_i = a \cdot r^{i-1}$$

Your task is to generate the first n elements of this sequence and output them as a comma-and-space separated string.

• For example, if a = 2, r = 3, and n = 4, the sequence is: 2, 6, 18, 54.

Please note that the program must read input from stdin and write the result to stdout.

inputFormat

The input consists of a single line containing three space-separated integers: a (the first term), r (the common ratio), and n (the number of terms).

outputFormat

Output a single line containing the first n elements of the geometric sequence, separated by a comma and a space.
