N-th Term Of GP
The first line of input contains an integer T denoting the number of queries or test cases. The first line of every test case contains three single space-separated integers N, A, and R denoting the term of GP series required, the first term, and the common ratio respectively.
For each test case, print an integer denoting the Nth term of GP in a separate line.
You do not need to print anything, it has already been taken care of. Just implement the given function.
1 <= T <= 10 1 <= N <= 10^8 0 <= A <= 50 0 <= R <= 100 Time limit: 1 second
