Answer to Question #203998 in Python for vinay

Question

Given two polynomials A and B, write a program that adds the given two polynomials A and B.Input

The first line contains a single integer M.

Next M lines contain two integers Pi, Ci separated with space, where Pi denotes power and Ci denotes co-efficient of Pi for polynomial A.

After that next line contains a single integer N.

Next N lines contain two integers Pj, Cj separated with space, where Pj denotes power and Cj denotes co-efficient of Pj for polynomial B.Output

Print the addition of polynomials A and B.

The format for printing polynomials is: Cix^Pi + Ci-1x^Pi-1 + .... + C1x + C0, where Pi's are powers in decreasing order, Ci is co-efficient and C0 is constant, there will be space before and after the plus or minus sign.

If co-efficient is zero then don't print the term.

if sum of polynomials is zero the output will be "0",

if "1" is the co-efficeint in sum of polynomials then neglect "1" in output

Answer 1

def add_polynomial(polynomial_A, polynomial_B,x,y):
    size = max(x,y)
    summation = [0 for row in range(size)]
    for n in range(0,x, 1):
        summation[n] = polynomial_A[n]
    for n in range(y):
        summation[n] += polynomial_B[n]
    return summation
def polynomial_display(polyno, a):
    for col in range(a):
        print(polyno[col], end= " ")
        if (col != 0):
            print("x^", col, end=" ")
        if (col != a - 1):
            print(" + ", end= " ")




R = []
T = []
m = int(input("Enter the size of the first polynomial\t"))

    R.append(int(y))

print("First polynomial is")
