input: Write a function to sort and print out the elements of an array of integers. The function should first sort the given array and then print the sorted array.
  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([3, 1, 4, 1, 5, 9, 2, 6, 5])==[1, 1, 2, 3, 4, 5, 5, 6, 9]
  assert sort_and_print([])==[]
  assert sort_and_print([100, 200, 300, 400])==[100, 200, 300, 400]
  assert sort_and_print([5, 4, 3, 2, 1])==[1, 2, 3, 4, 5]
