Problem Statement

Given are a prime number pp and a sequence of pp integers a0,,ap1a_0, \ldots, a_{p-1} consisting of zeros and ones.

Find a polynomial of degree at most p1p-1, $f(x) = b_{p-1} x^{p-1} + b_{p-2} x^{p-2} + \ldots + b_0$, satisfying the following conditions:

  • For each ii (0ip1)(0 \leq i \leq p-1), bib_i is an integer such that 0bip10 \leq b_i \leq p-1.
  • For each ii (0ip1)(0 \leq i \leq p-1), f(i)ai(modp)f(i) \equiv a_i \pmod p.

Constraints

  • 2p29992 \leq p \leq 2999
  • pp is a prime number.
  • 0ai10 \leq a_i \leq 1

Input

Input is given from Standard Input in the following format:

pp

a0a_0 a1a_1 \ldots ap1a_{p-1}

Output

Print b0,b1,,bp1b_0, b_1, \ldots, b_{p-1} of a polynomial f(x)f(x) satisfying the conditions, in this order, with spaces in between.

It can be proved that a solution always exists. If multiple solutions exist, any of them will be accepted.

f(x)=x+1f(x) = x + 1 satisfies the conditions, as follows:

  • f(0)=0+1=11(mod2)f(0) = 0 + 1 = 1 \equiv 1 \pmod 2
  • f(1)=1+1=20(mod2)f(1) = 1 + 1 = 2 \equiv 0 \pmod 2
