( 411 ) F Density of subarrays PROGRAMMING dp math 3400

B"Let c be some positive integer. Let's call an array a_1, a_2, ldots, a_n of positive integers c -array, if for all i condition 1 <= q a_i <= q c is satisfied. Let's call c -array b_1, b_2, ldots, b_k a subarray of c -array a_1, a_2, ldots, a_n , if there exists such set of k indices 1 <= q i_1 < i_2 < ldots < i_k <= q n that b_j = a_{i_j} for all 1 <= q j <= q k . Let's define density of c -array a_1, a_2, ldots, a_n as maximal non-negative integer p , such that any c -array, that contains p numbers is a subarray of a_1, a_2, ldots, a_n . You are given a number c and some c -array a_1, a_2, ldots, a_n . For all 0 <= q p <= q n find the number of sequences of indices 1 <= q i_1 < i_2 < ldots < i_k <= q n for all 1 <= q k <= q n , such that density of array a_{i_1}, a_{i_2}, ldots, a_{i_k} is equal to p . Find these numbers by modulo 998 ,244 ,353 , because they can be too large. The first line contains two integers n and c , separated by spaces ( 1 <= q n, c <= q 3 ,000 ). The second line contains n integers a_1, a_2, ldots, a_n , separated by spaces ( 1 <= q a_i <= q c ). Print n + 1 numbers s_0, s_1, ldots, s_n . s_p should be equal to the number of sequences of indices 1 <= q i_1 < i_2 < ldots < i_k <= q n for all 1 <= q k <= q n by modulo 998 ,244 ,353 , such that the density of array a_{i_1}, a_{i_2}, ldots, a_{i_k} is equal to p . In the first example, it's easy to see that the density of array will always be equal to its length. There exists 4 sequences with one index, 6 with two indices, 4 with three and 1 with four. In the second example, the only sequence of indices, such that the array will have non-zero density is all indices because in other cases there won't be at least one number "...
