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.

Sample Input

1 4
x**3 + x**2 + x + 1

Sample Output

True

Explanation

P(1)= 1³ + 1² + 1 + 1 = 4 = k
Hence, the output is True.
