( 382 ) I Interval-Free Permutations PROGRAMMING 2800

B'Consider a permutation p_1, p_2, ... p_n of integers from 1 to n . We call a sub-segment p_l, p_{l+1}, ... , p_{r-1}, p_{r} of the permutation an interval if it is a reordering of some set of consecutive integers. For example, the permutation (6,7,1,8,5,3,2,4) has the intervals (6,7) , (5,3,2,4) , (3,2) , and others. Each permutation has some trivial intervals -- the full permutation itself and every single element. We call a permutation interval-free if it does not have non-trivial intervals. In other words, interval-free permutation does not have intervals of length between 2 and n - 1 inclusive. Your task is to count the number of interval-free permutations of length n modulo prime number p . In the first line of the input there are two integers t ( 1 <= t <= 400 ) and p ( 10^8 <= p <= 10^9 ) -- the number of test cases to solve and the prime modulo. In each of the next t lines there is one integer n ( 1 <= n <= 400 ) -- the length of the permutation. For each of t test cases print a single integer -- the number of interval-free permutations modulo p . For n = 1 the only permutation is interval-free. For n = 4 two interval-free permutations are (2,4,1,3) and (3,1,4,2) . For n = 5 -- (2,4,1,5,3) , (2,5,3,1,4) , (3,1,5,2,4) , (3,5,1,4,2) , (4,1,3,5,2) , and (4,2,5,1,3) . We will not list all 28146 for n = 9 , but for example (4,7,9,5,1,8,2,6,3) , (2,4,6,1,9,7,3,8,5) , (3,6,9,4,1,5,8,2,7) , and (8,4,9,1,3,6,2,7,5) are interval-free. The exact value for n = 20 is 264111424634864638. '...
