# --description--
|
|
|
|
A root or zero of a polynomial P(x) is a solution to the equation P(x) = 0.
|
|
|
|
Define Pn as the polynomial whose coefficients are the digits of n.
|
|
|
|
For example, P5703(x) = 5x3 + 7x2 + 3.
|
|
|
|
We can see that:Pn(0) is the last digit of n, Pn(1) is the sum of the digits of n, Pn(10) is n itself.Define Z(k) as the number of positive integers, n, not exceeding k for which the polynomial Pn has at least one integer root.
|
|
|
|
It can be verified that Z(100 000) is 14696.
|
|
|
|
What is Z(1016)?

`euler269()` should return 1311109198529286.
|
|
|
|
```js
|
|
assert.strictEqual(euler269(), 1311109198529286);
|
|
```
