# --description--

Given an integer representing the number of years a couple has been married, return their most recent anniversary milestone according to this chart:

| Years Married | Milestone    |
| ------------- | ------------ |
| 1             | `"Paper"`    |
| 5             | `"Wood"`     |
| 10            | `"Tin"`      |
| 25            | `"Silver"`   |
| 40            | `"Ruby"`     |
| 50            | `"Gold"`     |
| 60            | `"Diamond"`  |
| 70            | `"Platinum"` |

- If they haven't reached the first milestone, return `"Newlyweds"`.

# --hints--

`get_milestone(0)` should return `"Newlyweds"`.

```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_milestone(0), "Newlyweds")`)
}})
```

`get_milestone(1)` should return `"Paper"`.

```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_milestone(1), "Paper")`)
}})
```

`get_milestone(8)` should return `"Wood"`.

```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_milestone(8), "Wood")`)
}})
```

`get_milestone(10)` should return `"Tin"`.

```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_milestone(10), "Tin")`)
}})
```

`get_milestone(26)` should return `"Silver"`.

```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_milestone(26), "Silver")`)
}})
```

`get_milestone(45)` should return `"Ruby"`.

```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_milestone(45), "Ruby")`)
}})
```

`get_milestone(50)` should return `"Gold"`.

```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_milestone(50), "Gold")`)
}})
```

`get_milestone(64)` should return `"Diamond"`.

```js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_milestone(64), "Diamond")`)
}})
```

`get_milestone(71)` should return `"Platinum"`.
