input: Write a function that implements the above sorting algorithm in Python and provides the specified outputs based on the sorted list of integers in ascending order. The function should take a list of integers as input and return the list sorted in ascending order.
  assert sort_ascending([3, 4, 5, 1, 2]) == [1, 2, 3, 4, 5]
  assert sort_ascending([3, 5, 10, 1, 2]) == [1, 2, 3, 5, 10]
  assert sort_ascending([4, 3, 1, 2]) == [1, 2, 3, 4]
  assert sort_ascending([3, 5, 4, 1, 2]) == [1, 2, 3, 4, 5]
  assert sort_ascending([]) == []
output: def sort_ascending(lst):
      return sorted(lst)
