# The Validator

> **[INCOMING — Mission Control, Earth]**
>
> Cadet, every system that takes user input has to *validate* it.
>
> Comparison operators (`>=`, `<`, `==`) return `True` or `False`
> directly. String methods like `.isupper()` and `.isdigit()` also
> return booleans:
>
> ```python
> len("hello") >= 8       # False
> "Hello"[0].isupper()    # True
> "abc1"[-1].isdigit()    # True
> ```
>
> Implement `validate(pw)` that returns a dict with four checks on
> a non-empty password:
>
> - `length` — char count (int)
> - `long_enough` — `length >= 8` (bool)
> - `starts_capital` — first char uppercase (bool)
> - `ends_digit` — last char a digit (bool)

## Your Task

In `starter/starter.py`, return the dict using `len()`, `>=`,
`.isupper()`, `.isdigit()`.

## Objectives

- All four keys present with correct types
- `validate("Andromeda1")` matches the expected dict exactly
- Works for any non-empty password
