input: Write a function to convert a list of integers to a dictionary where the keys are the integers from the list and the values are their corresponding words in English. The function should then iterate over the dictionary and print the values.
  
  assert convert_to_dict([1, 2, 3, 4]) == {'one', 'two', 'three', 'four'}
  assert convert_to_dict([5, 6, 7, 8]) == {'five', 'six', 'seven', 'eight'}
  assert convert_to_dict([]) == {}
output: def convert_to_dict(lst):
      num_to_word = {1: 'one', 2: 'two', 3: 'three', 4: 'four', 5: 'five', 6: 'six', 7: 'seven', 8: 'eight'}
      result = {num: num_to_word.get(num) for num in lst}
      for value in result.values():
          print(value)
      return set(result.values())
