# One is the loneliest number

## Task

The range of vision of a digit is its own value. `1` can see one digit to the left and one digit to the right,` 2` can see two digits, and so on.

Thus, the loneliness of a digit `N` is the sum of the digits which it can see.

Given a non-negative integer, your funtion must determine if there's at least one digit `1` in this integer such that its loneliness value is minimal.

## Example

```
number = 34315
```

digit | can see on the left | can see on the right | loneliness
--- | --- | --- | ---
3 | - | 431 | 4 + 3 + 1 = 8
4 | 3 | 315 | 3 + 3 + 1 + 5 = 12
3 | 34 | 15 | 3 + 4 + 1 + 5 = 13
1 | 3 | 5 | 3 + 5 = 8
5 | 3431 | - | 3 + 4 + 3 + 1 = 11

Is there a `1` for which the loneliness is minimal? Yes.
