POWPOW - Power with Combinatorics |
Your task is to find a^(exp^(b)),
a: Provided in input,10^5 => a >= 0
b: Provided in Input,10^5 => b >= 0
exp=(nC0)^2 + (nC1)^2 +(nC2)^2+ ... +(nCn)^2,
n: Provided in the input, 10^5 => n >= 0
As the answer can be too large , you need to output modulo 10^9+7.
nCr denotes n choose r.
Input
The first line of each input file contains number of test cases t (t<=1000).
Then follow a new line.
Then follow t lines, each containing 3 integers, (i.e. a b n in order) each of them separated by a space.
Output
Output Contains t lines, ith line contains the answer of the ith test case .
Example
Input: 1 1 1 1 Output: 1
Explanation
In First test case, the Value of exp is 2, value of 1^(2^1) is 1, so output is 1.

Time limit is too strict for non-imperative languages. We can have 1 more second to spare. :) |
