使用Python编写程序将作为链表的两个多项式相加假设我们有两个多项式,我们必须找出它们的加法。多项式必须被表示为链表;多项式的项将被表示为链表节点。每个链表节点将包含系数值、幂值和指向下一个链表节点的指针。我们必须返回一个第三个链表,它是两个链表多项式的和。
Following the idea of Multiplicative FFT, we split the polynomial $f(X)$ (of Degree 7) represented by $\mathcal{B}^{novel}$ into two polynomials with halved degrees: $$ \begin{split} f(X) &= a_0\mathcal{X}_0(X) + a_1\mathcal{X}_1(X) + \ldots + a_7\mathcal{X}_7...
1. Global trend lines One of the simplest methods to identify trends is to fit a ordinary least squares regression model to the data. The model most people are familiar with is the linear model, but you can add other polynomial terms for extra flexibility. In practice, avoid polynomials of...
