Given the A and R i,e first term and common ratio of a GP series. Find the Nth term of the series.
Input: A = 2, R = 2, N = 4 Output: 16 Explanation: The GP series is 2, 4, 8, 16, 32,... in which 16 is th 4th term.
Input: A = 4, R = 3, N = 3 Output: 36 Explanation: The GP series is 4, 12, 36, 72,.. in which 36 is the 3rd term.
You don't need to read or print anything. Your task is to complete the function Nth_term() which takes A, R and N as input parameter ans returns Nth term of the GP series modulo 109 + 7.
Expected Time Complexity: O(log2(N))
Expected Space Complexity: O(1)
1 <= A, R, N <= 1000000
