KBASEEN - Acceptable numbers

no tags 

Sitting in front of computer has made Byteasar's eye sight very bad. He has to wear glasses to fix it. But Byteasar doesn't like it. So everything associated with glasses is disliked by him.

Byteasar has been working with different numeral systems. When listing numbers, he knows exactly which of them aren't liked by him. Of course these numbers have two zeros next to each other. Now he is wondering: how many n-digits numbers in k-base numeral system he is able to accept. There could be many of them so print the result modulo m.


First there is a t (0 < t < 1001), number of test cases.
Each test contains three number: n (0 < n < 1018), k (1 < k < 1018) and m (1 < m < 1018). n is a length of the number, k - digits quantity in given numeral system.


For each test print answer divided modulo m.


4 2 100
3 10 10000

Output: 5

@vaibhav2303, see the description. Only two (or more) zeros are prohibited. Separate 0 is fine

Problem statement and/or the test cases is incorrect because when N=1, 0 is being considered as a accepted number which is not the case for other Ns.

I'm confused... what if k>10?

What is the answer when n==1? Do we consider 0 or not?
Edit: forgot to do %m when n==1.

@mahilewets. I don't know that problem or contest.
The idea of this problem was taken from the completely different source

Problem copied from Timus K-based numbers version 3

Edit: partially copied, concept is the same, statement is improved.

You give wrong answers for low cases. And there is something else. I'll investigate it later.
Avoiding overflow is one of the problem in this task.

Given the constraints, even long long will give WA. Why keep constraints like that?
Edit: I did submit in Python to avoid overflow. Still getting WA. Can you please check?

Would have been a little trickier if it he accepted only those with "00".
