Answer to Question #190326 in Python for Hari nadh babu

Question

Add two polynomials

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

Output

Print the addition of polynomials A and B.

If the degree of polynomial is zero and the constant term is also zero, then just print 0 to represent the polynomial.

Test Case 1:-

Input:-

6

0 -20

1 23

2 30

3 19

4 6

5 17

9

0 -100

5 -89

6 -20

7 -1

1 20

2 4

3 99

4 -45

8 12

Output:-

12x^8 - x^7 - 20x^6 - 72x^5 - 39x^4 + 118x^3 + 34x^2 + 43x - 120

Note :- Need Space between - and + operators

Test Case 2:-

Input:-

4

0 5

1 0

2 10

3 6

3

0 1

1 2

2 4

Output :-

6x^3 + 14x^2 + 2x + 6

Note:- Need Space between - and + operators

Test Case 3:- Test Case 4:-

Input:- Input:-

5 4

0 -2 0 5

3 6 1 0

4 7 2 10

1 -3 3 6

2 -1 4

5 0 -5

0 1 1 0

1 2 2 -10

2 -4 3 -6

3 3 Output:-

4 5 0

Output:-

12x^4 + 9x^3 - 5x^2 - x - 1

Note:- Need Space between - and + operators

We need all 4 test cases can be came when code was run. I want exact outputs for all test cases

Answer 1

# enter dataset polinom
print('Plolinom A data entry')
n = int(input('Enter the number of N polynomial members '))
polinom_a =[0 for item in range(n)]
for item in range(n):
    p, c = input('Enter separated by space Pi and Ci ').split(' ')
    polinom_a[int(p)] = int(c)
m = int(input('Enter the number of M polynomial members '))
polinom_b =[0 for item in range(m)]
print('Plolinom B data entry')
for item in range(m):
    p, c = input('Enter separated by space Pi and Ci ').split(' ')
    polinom_b[int(p)] = int(c)
# define references to polynomials of greater and lesser length
pol_max , pol_min = polinom_a , polinom_b
if len(pol_min) > len(pol_max):
    pol_max , pol_min = polinom_b , polinom_a 
# add the coefficients of the polynorms in pairs
for item in range(len(pol_min)):
    pol_max[item] += pol_min[item]
# result output
for item in range(len(pol_max)-1,0,-1):
    if item == 0:
        continue
    print (f'{pol_max[item]}x^{item} + ',end='')
print(pol_max[0])
