FRSKT - Fibonacci recursive sequences (medium)
Let FIB the Fibonacci function :
FIB(0)=0 ; FIB(1)=1
and
for N>=2 FIB(N) = FIB(N-1) + FIB(N-2)
Example : we have FIB(6)=8, and FIB(8)=21.
Let F(K, N) a new function:
F(0, N) = N for all integers N.
F(K, N) = F(K-1, FIB(N) ) for K>0 and all integers N.
Example : F(2, 6) = F(1, FIB(6) ) = F(0, FIB( FIB(6) ) ) = FIB( FIB(6) ) = FIB(8) = 21
Input
The input begins with the number T of test cases in a single line.
In each of the next T lines there are three integers: K, N, M.
Output
For each test case, print F(K, N),
as the answer could not fit in a 64bit container,
give your answer modulo M.
Example
Input: 3 4 5 1000 3 4 1000 2 6 1000 Output: 5 1 21
Constraints
1 <= T <= 10^3 0 <= K <= 10^2 0 <= N <= 10^9 2 <= M <= 10^9
You would perhaps have a look, after, at the hard edition with more difficult constraints.
Edit 2017-02-11, after compiler update. My old Python code ends in 0.08s. New TL.
