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.
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 conating 3 integers,(i.e a b n in order) each of them seperated by a space.
Output Contains t lines,ith line conatins the answer of the ith test case .
1 1 1
Explanation: In First test case, the Value of exp is 2, value of 1^(2^1) is 1,so output is 1.
Can you provide some more test cases for big values og a,b and n?
is there any special case....why i get wrong answer at running judge 8??
@Devendra: Thanks for your response. But for me the original version of the problem is more interesting. I don't know how you feel about it -- whether you would be willing to change it back to a^b^exp (but with corrected test data), or maybe have a^b^exp version added as a separate problem. If you can't solve a^b^exp version at this time, maybe I could add it (I haven't solved it yet, but I know a way), although I prefer to be able to compete on it. Also I think it's worth reiterating Francky's earlier comment about whether the time limit is appropriate for slower languages like Python.
@Francky,Mitch Schwartz:Thanks for pointing out the error,actually i thought for a^(exp^b) bt what lead me to calculate a^(b^exp) with same logic has no explanation,I apologize to all the users who put up their valuable time to solve that one,I hope that this one is a correct one.
