Task

You are given a polynomial P of a single indeterminate (or variable), x.
You are also given the values of x and k. Your task is to verify if P(x)=k.

Input Format

The first line contains the space separated values of x and k.
The second line contains the polynomial P.

Output Format

Print True if P(x)=k . Otherwise, print False.

 

=> 독립변수 x와 다항식 P, k값을 줄건데 P(x)=k 의 불린값을 출력하라

x, k = map(int, input().split())
P = input()


def poly(x, k):
    calcul = eval(P)
    return calcul == k

print(poly(x, k))

x, k= map(int,input().split())

print(eval(input())==k)
