input: Write a function to create a lambda expression in Python that filters a list of integers greater than 50. The function should take a list of integers as input and return the filtered list.
  assert filter_above_50([45, 12, 52, 89, 33, 99]) == [52, 89, 99]
  assert filter_above_50([10, 20, 30, 40, 50, 60]) == [60]
  assert filter_above_50([70, 80, 90, 100]) == [70, 80, 90, 100]
  assert filter_above_50([49, 50, 51]) == [51]
  assert filter_above_50([50, 50, 50]) == []
output: return list(filter(lambda x: x > 50, lst))
