The challenge

Finish the solution so that it sorts the passed-in array/list of numbers. If the function passes in an empty array/list or null/None value then it should return an empty array/list.

Examples:

1
2

solution([1,2,3,10,5]) # should return [1,2,3,5,10]
solution(None) # should return []

The solution in Python code

Option 1:

1
2
3
4

def solution(nums):
    if not nums:
        return []
    return sorted(nums)

Option 2:

1
2

def solution(nums):
    return sorted(nums) if nums else []

Option 3:

1
2

def solution(nums):
    return sorted(nums or [])
