题目描述
This is the easy version of the problem. The only difference between the three versions is the constraints on n and k . You can make hacks only if all versions of the problem are solved.
Maxim is a minibus driver on Venus.
To ride on Maxim's minibus, you need a ticket. Each ticket has a number consisting of n digits. However, as we know, the residents of Venus use a numeral system with base k , rather than the decimal system. Therefore, the ticket number can be considered as a sequence of n integers from 0 to k−1 , inclusive.
The residents of Venus consider a ticket to be lucky if there is a digit on it that is equal to the sum of the remaining digits, modulo k . For example, if k=10 , then the ticket 7135 is lucky because 7+1+5≡3(mod10) . On the other hand, the ticket 7136 is not lucky because no digit is equal to the sum of the others modulo 10 .
Once, while on a trip, Maxim wondered: how many lucky tickets exist? At the same time, Maxim understands that this number can be very large, so he is interested only in the answer modulo some prime number m .
输入格式
The only line of the input contains three integers n , k and m ( 1≤n≤100 , 1≤k≤30 , 108≤m≤109+7 , m is a prime number) — the number of digits on the ticket, the base of the numeral system on Venus, and the module for answer calculation.
输出格式
Print one integer — the number of lucky tickets modulo m , i. e. the remainder after dividing the answer by m .
