Algorithm
Problem Name: Python -
In this HackerRank Functions in PYTHON problem solution,
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.
