input: Write a function to sort and print out the elements of an array of integers. The function should take a list of integers as input and return the sorted list. 
  assert sort_and_print([17, 41, 5, 22, 54, 6, 29, 3, 13]) == [3, 5, 6, 13, 17, 22, 29, 41, 54]
  assert sort_and_print([9, 3, 6, 1, 5]) == [1, 3, 5, 6, 9]
  assert sort_and_print([]) == []
  assert sort_and_print([2, 2, 2, 2]) == [2, 2, 2, 2]
  assert sort_and_print([-3, -1, -2]) == [-3, -2, -1]
output: def sort_and_print(arr):
      return sorted(arr)
