Describe what this function does. Try different numbers as input.

Question

```
def test(num):
if num > 0:
return test(num -2) * test(num -1)
else:
return 0
```

Answer 1

This method recursively calls itself by calling itself each time that the passed in num is above 0, with one cal decrementing the num once and one twice. None of this has any impact though as 0 times anything is still 0 so any number passed in will be 0.
