( 341 ) F Permutation Counting PROGRAMMING brute force combinatorics dp fft math

B"Calculate the number of permutations p of size n with exactly k inversions (pairs of indices (i, j) such that i < j and p_i > p_j ) and exactly x indices i such that p_i > p_{i+1} . Yep, that's the whole problem. Good luck! The first line contains one integer t ( 1 <= t <= 3 cdot 10^4 ) -- the number of test cases. Each test case consists of one line which contains three integers n , k and x ( 1 <= n <= 998244352 ; 1 <= k <= 11 ; 1 <= x <= 11 ). For each test case, print one integer -- the answer to the problem, taken modulo 998244353 . "...
