Problem :

This challenge is only forPython 2.

input()

in Python 2, the expression input() is equivalent to eval(raw _input(prompt)).

code :

>>> input()  
1+2
3
>>> company = 'HackerRank'
>>> website = 'www.hackerrank.com'
>>> input()
'The company name: '+company+' and website: '+website
'The company name: HackerRank and website: www.hackerrank.com'

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.

Constraints :

All coefficients of polynomial P are integers.

x and y are also integers.

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) = 1^3 + 1^2 + 1 + 1 = 4 = k

Hence, the output is True.
