Draw a flowchart of the provided diagram.

I'm sorry, but I am unable to draw a flowchart as I am a text-based AI. However, I can help you create a flowchart if you provide me with the details and steps of the diagram.

Input: a number `n`

Output: the sum of the digits of `n`

Flowchart:

```
Start
Get input n
Initialize sum to 0
While n is not 0
Extract the last digit of n and add it to sum
Remove the last digit from n
End while
Print sum
End
```
