input: Write a function to create a lambda expression in Python to filter a list of integers greater than 50. If the list is empty, return an empty list.
  assert filter_list_gt_50([45, 12, 52, 89, 33, 99])==[52, 89, 99]
  assert filter_list_gt_50([])==[]
  assert filter_list_gt_50([45, 12, 33])==[]
  assert filter_list_gt_50([55, 60, 65])==[55, 60, 65]
  assert filter_list_gt_50([50, 51, 49])==[51]
output: def filter_list_gt_50(lst):
      return list(filter(lambda x: x > 50, lst))
