[split] problem with function return value

[buran]

There are multitude of problems in your code, for start:
1. remove lines 1 and 2 - you don't need them
2. dedent lines 16 and 17, so that they are not part of the function
3. You need to convert num to int, because input will returns str
4. You need to pass num (after being converted to int) as argument when calling the function on line 17

Note, this will not resolve problems with the logic you implement (i.e. there are more problems in the code)
