input: Write a python function to filter numbers greater than 50 using a lambda function.
  assert filter_greater_than_fifty([45, 12, 52, 89, 33, 99]) == [52, 89, 99]
  assert filter_greater_than_fifty([10, 55, 60, 45, 30, 75]) == [55, 60, 75]
  assert filter_greater_than_fifty([1, 2, 3, 4, 5]) == []
output: def filter_greater_than_fifty(numbers):
      return list(filter(lambda x: x > 50, numbers))
