# The Translator

> Cadet, when input comes in as text (a `str`), you can't do math

> - `float("3.14")` → `3.14`
> - `str(42)` → `"42"`

> Implement `years_until(age)` that returns `100 - age` as an `int`.

## Your Task

Open `starter/starter.py`. Convert `age` with `int()`, then return
`100 - age`.

## Objectives

- `years_until(25)` returns `75`
- `years_until("25")` also returns `75` (handles string input)
- Works for any integer age 0–100
