    FAST Fourier Transform (FFT) Algorithm

    hey i try to solve a task, but i dont get it

    Compute the coefficient repr. of (p(x)) by using FFT algorithm.
    p(x) = 2x^3 - x + 4x + 1


    this is the way i wanted to started(i dont know if I am right)

    i have a input with length N = 4 its Array a [2, -1, 4, 1]
    then i split them in odd and even
    d[0] = FFT([-1,1])
    d[1] = FFT([2, 4])

    i dont know how to proceed further, every help would be appreciated
