Algorithm
Problem Name:
In this HackerRank Functions in Java programming problem solution,
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 + ....+ 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
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
