Suppose there is a vector v like [1 0 0 -1], representing polynomial coefficients.
In this example, the polynimial is 1*x^3+0*x^2+0*x-1 or (x^3-1).
Suppose there is another vector w like [1 -1].
In this example, the second polynomial is (x-1).
If x is any integer then the polynomial represented by (v/w) is integer?

This problem needs to have its description fixed. It should be "Is the polynomial represented by (v/w) an integer for any integer x except for the roots of w? if the integer x is a root of w, we will have a NaN, which is the case for the test case #1 and the value x=1 for instance.
