Types

type Poly

type Poly []*big.Int

Data structure for a polynomial Just an array in Reverse f(x) = 3x^3 + 2x + 1 => [1 2 0 3]

func (Poly) GetDegree

func (p Poly) GetDegree() int

GetDegree returns the degree if p = x^3 + 2x^2 + 5, GetDegree() returns 3

func (Poly) Mul

func (p Poly) Mul(q Poly, m *big.Int) Poly

P * Q

func (Poly) String

func (p Poly) String() (s string)

pretty print

func (Poly) Sub

func (p Poly) Sub(q Poly, m *big.Int) Poly

Sub() subtracts P from Q Since we already have Add(), Sub() does Add(P, -Q)
