B'There is a number x initially written on a blackboard. You repeat the following action a fixed amount of times: Determine the distribution of final number given the distribution of initial number and the number of steps. The first line contains two integers, N (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89N xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89105) -- the maximum number written on the blackboard -- and M (0 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89M xe2 x80 x89 xe2 x89 xa4 xe2 x80 x891018) -- the number of steps to perform. The second line contains N xe2 x80 x89+ xe2 x80 x891 integers P0, xe2 x80 x89P1, xe2 x80 x89..., xe2 x80 x89PN (0 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89Pi xe2 x80 x89< xe2 x80 x89998244353), where Pi describes the probability that the starting number is i. We can express this probability as irreducible fraction P xe2 x80 x89/ xe2 x80 x89Q, then . It is guaranteed that the sum of all Pis equals 1 (modulo 998244353). Output a single line of N xe2 x80 x89+ xe2 x80 x891 integers, where Ri is the probability that the final number after M steps is i. It can be proven that the probability may always be expressed as an irreducible fraction P xe2 x80 x89/ xe2 x80 x89Q. You are asked to output . In the first case, we start with number 2. After one step, it will be 0, 1 or 2 with probability 1/3 each. In the second case, the number will remain 2 with probability 1/9. With probability 1/9 it stays 2 in the first round and changes to 1 in the next, and with probability 1/6 changes to 1 in the first round and stays in the second. In all other cases the final integer is 0. '... |
