## 39. Armstrong Number

Write a function `solve` that checks if an integer is an Armstrong number (a.k.a [Narcissistic number](https://en.wikipedia.org/wiki/Narcissistic_number)).

**Example:** `Input: 153` `Output: True` `Explanation: 1^3 + 5^3 + 3^3 = 153`

Make sure you `return` your solution, don't print!

```python
def solve(num):
    pass
```
