input: Write a function to print all the elements greater than 50 from a given list. The function should take a list of numbers as input and print each element that satisfies the condition.
  assert greater_than_50([2, 60, 5, 4, 78, 32, 99])
  assert greater_than_50([10, 20, 30, 40, 50, 60, 70])
  assert greater_than_50([51, 52, 53, 54, 55])
  assert greater_than_50([1, 2, 3, 4, 5])
  assert greater_than_50([])
output: def greater_than_50(numbers):
      for num in numbers:
          if num > 50:
              print(num)
