input: Write a function to filter a list of integers and return a new list containing only the values greater than 50. The function should use a lambda expression to perform the filtering.
  
  filtered_list = lambda lst: list(filter(lambda x: x > 50, lst))
  
  assert filtered_list([45, 12, 52, 89, 33, 99]) == [52, 89, 99]
  assert filtered_list([25, 75, 30, 85, 10]) == [75, 85]
  assert filtered_list([33, 44, 55]) == [55]
  assert filtered_list([10, 20, 30, 40]) == []
  assert filtered_list([]) == []
output: filtered_list = lambda lst: list(filter(lambda x: x > 50, lst))
