# The Mirror

> **[INCOMING — Mission Control, Earth]**
>
> Cadet, a *palindrome* reads the same forwards and backwards.
> `racecar`. `level`. `madam`.
>
> A reverse-slice flips a string in one move:
>
> ```python
> "Hello"[::-1]    # "olleH"
> ```
>
> A string is a palindrome when it equals its reverse. The `==`
> operator returns `True` or `False` directly.
>
> Implement `mirror(s)` that returns a dict with three keys:
>
> - `original` — the input
> - `reversed` — the input reversed
> - `palindrome` — `True` if equal to its reverse
>
> Match case exactly — `racecar` and `RaceCar` are different inputs.

## Your Task

In `starter/starter.py`, build the dict using `[::-1]` and `==`.

## Objectives

- `mirror("racecar")["palindrome"]` is `True`
- `mirror("hello")["palindrome"]` is `False`
- All three keys correct for any input string
